At Android, we want to make it as easy as possible for developers to create the most helpful apps for their users. That’s why we aim to provide the best location experience with our APIs like the Fused Location Provider API (FLP). However, we’ve heard from many of you that the biggest location issue is inaccuracy in dense urban areas, such as wrong-side-of-the-street and even wrong-city-block errors.
This is particularly critical for the most-used location apps, such as rideshare and navigation. For instance, when users request a rideshare vehicle in a city, apps cannot easily locate them because of the GPS errors.
The last great unsolved GPS problem
This wrong-side-of-the-street position error is caused by reflected GPS signals in cities, and we embarked on an ambitious project to help solve this great problem in GPS. Our solution uses 3D mapping aided corrections, and is only feasible to be done at scale by Google because it comprises 3D building models, raw GPS measurements, and machine learning.
The December Pixel Feature Drop adds 3D mapping aided GPS corrections to Pixel 5 and Pixel 4a (5G). With a system API that provides feedback to the Qualcomm Snapdragon 5G Mobile Platform that powers Pixel, the accuracy in cities (urban canyons) improves spectacularly.

Pictures above show a pedestrian test, with Pixel 5 phone, walking along one side of the street, then the other. Yellow = Path followed, Red = without 3D mapping aided corrections, Blue = with 3D mapping aided corrections.
Why hasn’t this been solved before?
The problem is that GPS constructively locates you in the wrong place when you are in a city. This is because all GPS systems are based on line-of-sight operation from satellites. But in big cities, most or all signals reach you through non line-of-sight reflections, because the direct signals are blocked by the buildings.

(Image: Frank van Diggelen)Image: Frank van Diggelen
The GPS chip assumes that the signal is line-of-sight and therefore introduces error when it calculates the excess path length that the signals traveled. The most common side effect is that your position appears on the wrong side of the street, although your position can also appear on the wrong city block, especially in very large cities with many skyscrapers.
There have been attempts to address this problem for more than a decade. But no solution existed at scale, until 3D mapping aided corrections were launched on Android.
How 3D mapping aided corrections work
Image: Frank van Diggelen
The 3D mapping aided corrections module, in Google Play services, includes tiles of 3D building models that Google has for more than 3,850 cities around the world. Google Play services 3D mapping aided corrections currently supports pedestrian use-cases only. When you use your device’s GPS while walking, Android’s Activity Recognition API will recognize that you are a pedestrian, and if you are in one of the 3,850+ cities, tiles with 3D models will be downloaded and cached on the phone for that city. Cache size is approximately 20MB, which is about the same size as 6 photographs.
Inside the module, the 3D mapping aided corrections algorithms solve the chicken-and-egg problem, which is: if the GPS position is not in the right place, then how do you know which buildings are blocking or reflecting the signals? Having solved this problem, 3D mapping aided corrections provide a set of corrected positions to the FLP. A system API then provides this information to the GPS chip to help the chip improve the accuracy of the next GPS fix.
With this December Pixel feature drop, we are releasing version 2 of 3D mapping aided corrections on Pixel 5 and Pixel 4a (5G). This reduces wrong-side-of-street occurrences by approximately 75%. Other Android phones, using Android 8 or later, have version 1 implemented in the FLP, which reduces wrong-side-of-street occurrences by approximately 50%. Version 2 will be available to the entire Android ecosystem (Android 8 or later) in early 2021.
Android’s 3D mapping aided corrections work with signals from the USA’s GPS as well as other GNSS: GLONASS, Galileo, BeiDou, and QZSS.
Our GPS chip partners shared the importance of this work for their technologies.
Francesco Grilli, vice president of product management at Qualcomm Technologies Inc.:
“Consumers rely on the accuracy of the positioning and navigation capabilities of their mobile phones. Location technology is at the heart of ensuring you find your favorite restaurant and you get your rideshare service in a timely manner. Qualcomm Technologies is leading the charge to improve consumer experiences with its newest Qualcomm Location Suite technology featuring integration with Google’s 3D mapping aided corrections. This collaboration with Google is an important milestone toward sidewalk-level location accuracy.”
Charles Abraham, senior director of engineering, Broadcom Inc.:
“Broadcom has integrated Google’s 3D mapping aided corrections into the navigation engine of the BCM47765 dual-frequency GNSS chip. The combination of dual frequency L1 and L5 signals plus 3D mapping aided corrections provides unprecedented accuracy in urban canyons. L5 plus Google’s corrections are a game-changer for GNSS use in cities.”
Yenchi Lee, deputy general manager of MediaTek’s Wireless Communications Business Unit:
“Google’s 3D mapping aided corrections is a major advancement in personal location accuracy for smartphone users when walking in urban environments. MediaTek’s Dimensity 5G family enables 3D mapping aided corrections in addition to its highly accurate dual-band GNSS and industry-leading dead reckoning performance to give the most accurate global positioning ever for 5G smartphone users.”
How to access 3D mapping aided corrections
Android’s 3D mapping aided corrections automatically works when the GPS is being used by a pedestrian in any of the 3850+ cities, on any phone that runs Android 8 or later. The best way for developers to take advantage of the improvement is to use FLP to get location information. The further 3D mapping aided corrections in the GPS chip are available to Pixel 5 and Pixel 4a (5G) today, and will be rolled out to the rest of the Android ecosystem (Android 8 or later) in the next several weeks. We will also soon support more modes including driving.
Android’s 3D mapping aided corrections cover more than 3850 cities, including:
North America: All major cities in USA, Canada, Mexico.
Europe: All major cities. (100%, except Russia & Ukraine)
Asia: All major cities in Japan and Taiwan.
Rest of the world: All major cities in Brazil, Argentina, Australia, New Zealand, and South Africa.
As our Google Earth 3D models expand, so will 3D mapping aided corrections coverage.
Google Maps is also getting updates that will provide more street level detail for pedestrians in select cities, such as sidewalks, crosswalks, and pedestrian islands. In 2021, you can get these updates for your app using the Google Maps Platform. Along with the improved location accuracy from 3D mapping aided corrections, we hope we can help developers like you better support use cases for the world’s 2B pedestrians that use Android.
Continuously making location better
In addition to 3D mapping aided corrections, we continue to work hard to make location as accurate and useful as possible. Below are the latest improvements to the Fused Location Provider API (FLP):
Developers wanted an easier way to retrieve the current location. With the new getCurrentLocation() API, developers can get the current location in a single request, rather than having to subscribe to ongoing location changes. By allowing developers to request location only when needed (and automatically timing out and closing open location requests), this new API also improves battery life. Check out our latest Kotlin sample.
Android 11’s Data Access Auditing API provides more transparency into how your app and its dependencies access private data (like location) from users. With the new support for the API’s attribution tags in the FusedLocationProviderClient, developers can more easily audit their apps’ location subscriptions in addition to regular location requests. Check out this Kotlin sample to learn more.

The huge current investment in deploying 5G mobile networks is promoted by setting high expectations for significantly increased throughput and reduced latency.
This can only be realized by deploying the network radios close to the users, especially for the millimeter-wave frequencies with their short propagation distance.
This also means a high density of radios, often imbedded within macro coverage.
To coordinate seamless functioning, network synchronization accuracy must be much higher than with legacy deployments, according to Optical Zonu. The greatly enhanced data throughput with advanced features such as aggregation, massive multiple-input/multiple-output (MIMO) and beam steering require highly accurate network timing and phase coordination.
Small cells close to a network’s edge are usually far from the hub where the grandmaster timing server generates the PTP timing signal and sends it to the network edge over the Ethernet backhaul. The long runs require multiple hops through routers and switches. Each of these adds dynamically changing packet delays depending on network loading. Also, there are inevitable asymmetries between the upstream and downstream packet delays. These timing errors can result in a drastically reduced network performance.
One way to correct these timing errors is to connect an edge grandmaster server at the small cell location connected to the local backhaul router. Connecting the GPS directly to each of the small cells is the other way.
The GPS approach is simple in concept, but has been problematic since, with small cells distributed in the facility, many or all the units can be far from a window where a GPS antenna could be mounted.
Optical Zonu, a U.S. carrier-approved supplier of RF-over-fiber transport solutions, has solved this problem with its GPS at the Edge kit. The GPS-over-fiber solution distributes GPS to each small-cell location alongside the backhaul.
A compact GPS fiber antenna unit connects to a GPS antenna on the roof. A single cable connection to this unit provides power to the unit and brings the fiber-optic connection to an optical splitter, which is collocated with the local router for the small-cell backhaul.
The fibers from this splitter are routed along with the backhaul cable to each small-cell location, where they each connect to a small fiber base unit that recovers the GPS signal and connects it to the auxiliary GPS port on each small cell.
Optical Zonu offers two variants.
Small cells with fiber-optic backhaul. Higher power cells typically use a fiber-optic backhaul and require local AC power. In this case, one of the fibers in the cable to each small cell is used for the GPS connection, and each base unit connects to the local AC power with an adapter. In this case, the only additional cable needed is the single run to the rooftop.
Diagram: Optical Zonu
Small cells with a CATx backhaul. This setup is typical for lower power small cells. In this architecture, a single fiber is pulled along with the CAT6 backhaul cable. A single hybrid fiber/CAT6 cable can also be used. The fiber is connected to a small fiber base unit at each small cell to recover the GPS signal, which is connected to the small cell auxiliary GPS port. The CAT6 is also connected to the fiber base unit. The backhaul is passed through from the small cell, and the PoE++ is tapped to power the base unit. Once again, the only additional cable pull is the single run to the rooftop antenna — local power isn’t needed at every small cell location.
Diagram: Optical Zonu
The Optical Zonu GPS at the Edge kit provides an easy-to-install and cost-effective solution that guarantees the highest timing and phase accuracy for a network that is vendor agnostic and, as with the edge grandmaster approach, still has the central PTP as a backup.
New modules enable entertainment, advanced connectivity features and next-generation artificial intelligence
Qualcomm Technologies has launched three new mobile platforms — the Qualcomm Snapdragon 720G, 662 and 460 — to enable enhanced user experiences across connectivity, gaming and entertainment.
The new mobile platforms support dual-frequency (L1 and L5) GNSS to improve location positioning accuracy and robustness. The system-on-chip solutions also support the Indian NavIC (Navigation with Indian Constellation).

The device combines u-blox GNSS, 4G and Wi-Fi technology, eliminating the need to equip vehicles with a separate mobile Wi‑Fi hotspot.
According to the companies, the StartLink TrackerWi‑Fi is suitable for applications for connected cars, telematics, vehicle diagnostics, fleet management, vehicle security, usage-based insurance, and rental and leasing service companies.
The internet of things (IoT) and connected-car initiatives are providing rental car companies and transportation and logistics firms with tools to track vehicles, preemptively detect and diagnose disturbances from a distance, and monitor the behavior of their drivers in real time. ERM has more than 1.8 million vehicle fleet-tracking devices deployed on roads world-wide.
As onboard Wi‑Fi becomes increasingly widespread, many companies are fitting vehicles with Wi‑Fi hotspots to offer drivers and passengers internet access. With its integrated Wi‑Fi hotspot, ERM’s StarLink TrackerWi‑Fi lets users tap into the cellular 4G connectivity to transfer telematics data to the fleet manager. This makes it possible to send real-time telematics data to the driver’s smart device or onboard infotainment system, and it also reduces the number of SIM cards needed from one per device to one per vehicle.
Sourcing the GNSS tracking, cellular 4G LTE, and Wi‑Fi technology from u-blox played a key role in achieving the device’s fast time to market. By using u‑blox’s pre-tested positioning and communications modules with integrated software, the manufacturer was able to cut the time needed for production and development by several months.
“We saw an opportunity to provide more values to our customers by adding Wi‑Fi hot spot functionality to our StarLink Tracker, our leading telematics product, but knew that we had to be quick to stay ahead of the game,” said Kfir Lavi, senior vice president of ERM Advanced Telematics.
“Our partners are always at the top of our priorities, and we are working to adapt our offerings to the market demands and the changing needs of their customers. Working with u‑blox as the provider of the positioning and wireless communication technology helped us move from concept to commercialization in under six months and provide our partners with an advanced product in a short time,” Lavi said.
“This successful collaboration demonstrates that we have evolved from a provider of individual technologies, namely GNSS positioning, cellular 4G connectivity, or short range radio communication, to a provider of solutions that bundle these technologies,” said Thomas Seiler, CEO of u-blox. “We are seeing increased demand for such bundled solutions and are convinced that the close integration of our technology portfolio offers our customers the unique ability to jump-start even challenging projects on extremely short notice.”

Automotive technology provider ERM Advanced Telematics has launched the StarLink Tracker with Wi-Fi, which integrates advanced vehicle tracking, driver behavior monitoring, theft prevention, Bluetooth, Wi-Fi and 4G cellular capabilities in a single device.
The company’s products have been installed in more than 1.5 million vehicles worldwide, the company said.
The StarLink Tracker with Wi-Fi is the first product under ERM’s new Wireless Connect strategy, which aims to use wireless technologies to provide its partners — vehicle fleet management companies, vehicle manufacturers and importers and car insurance companies — with a competitive edge.
The StarLink Tracker is a modular solution that is designed for installation both in vehicles on the production line and in the aftermarket, for vehicles that have left the production line. It turns any vehicle in which it is installed into a connected car.
The modularity of the product allows the addition of capabilities anytime through the use of add-on products provided by ERM or by a third party. This can be done on demand and without any need to replace the StarLink Tracker device, which keeps functioning as the central tracking and communications unit under any such solution.
The StarLink Tracker with Wi-Fi took about a year to develop, and ERM has already received its first orders to supply the product from customers in the United States, India and Australia.
The 120-gram tracker creates Wi-Fi hotspots in the vehicle for up to eight devices. It features a GPS/GLONASS/Galileo location module and an ability to navigate inside underground parking lots or in mines; a 4G cellular modem; internal antennas, emergency button support and built-in data logger.
Other capabilities are internal management of up to 500 driver IDs, remote immobilization, wireless connectivity to a wide range of additional ERM and third-party products and many other features.
As the core infrastructure for a Connected Car applications, the product can integrate to full range of the vehicle’s internet connectivity needs, which are provided by the use of the tracking unit’s SIM card without the need for any additional SIM card, the company said.
The StarLink Tracker with Wi-Fi and products that ERM Advanced Telematics will launch in the future under its Wireless Connect strategy, can be installed using the installer’s standard smartphone which communicates through Bluetooth connection in order to configure the product and perform any required adaptations. All this can be much faster compared to many other telematics devices and with much less hassle that might have arised due to the need to hook-up and hide wires.
The StarLink Tracker with Wi-Fi is also equipped with a microphone and loudspeaker to initiate and receive calls and dial emergency numbers. One application for this can be E-Call (Emergency Call), such as in the European Union or just as an Emergency Call application.
When pressing the location unit’s emergency button or immediately after an impact above a certain intensity, the unit will allows conversation between the vehicle’s occupants and the emergency center personnel, who can hear what is happening in the vehicle and identify events such as threats against the driver or accidents.
The product will also provide information about the driver’s behavior, including careless driving, accidents, off-road driving, acceleration during turns, speed violations and more, information that can be used by the manager to significantly improve fleet management capabilities, performance and can decrease operational expenses.
The cellular 5G standard targets latencies under 1 millisecond, data rates of up to 10 gigabits per second, extremely high network reliability and better accuracy in positioning. With location awareness becoming an essential feature in many new markets, positioning is considered as an integral part of the system design of upcoming 5G mobile networks.
The cellular industry is currently implementing Long-Term Evolution (LTE)-Advanced, which might be called “4G” mobile broadband. Simultaneously, the industry is preparing the next step, a fifth-generation (5G) system. It will process communication 10 times faster than 4G, according to experts. 5G rollout will be complete in many international metropolitan areas by 2020.

Adaptive array antennas
In addition to the precise positioning it will afford, 5G shares another characteristic with GPS/GNSS: adaptive array antennas for digital beamforming (DBF). Adaptive arrays have many advantages for PNT, primarily in mitigation for multipath, jamming and spoofing.
Emerging applications of DBF in 5G involve dense networks of picocells, small cellular base stations that typically cover a small indoor area. Picocells extend coverage where outdoor signals do not reach well, and add network capacity in areas with very dense phone usage. 5G architectures will use adaptive array technology to achieve high data rates, spectrum reuse and communications robustness.
The implications for PNT are that 5G will require improved (relative) PNT to operate effectively, and picocells will be a source of PNT information in constrained environments.
5G involves massive directional communications via multiple-input, multiple-output (MIMO), enabling high-bandwidth communications in fading (multipath) channels by using multiple antenna inputs to adapt to channels. It can do this without knowledge of user location, but it adds to the processing complexity. The directional capability can enable multiple users to be serviced in a picocell at different frequencies, while permitting spectrum re-use by nearby picocells through narrow beamwidth and the limited range of millimeter-wave (mmWave) frequencies.
The PNT implications of 5G architectures, according to Gary McGraw of Rockwell Collins, are that 5G picocells will be synergistic with PNT in challenged environments — naturally, indoor and dense urban. They will necessitate development of distributed, networked PNT processing and infrastructure.
Fraunhofer
The 5G positioning framework will integrate a multitude of sensors into a hybrid positioning scheme, according to the Fraunhofer Institute for Integrated Circuits (IIS) in Germany. Fraunhofer IIS is currently prototyping low-latency and high-precision positioning systems for legacy LTE and future 5G New Radio (5G NR).
5G NR enables positioning by providing high bandwidths for precise timing, new frequency bands at mmWave, massive MIMO for accurate angle-of-arrival estimation and new architectural options that support positioning. Improved accuracy, robustness and latency can be achieved, according to the institute.
5G provides fast and reliable access to moving objects to achieve time-critical process control and optimization in industrial environments. Increased contextual awareness of goods, parts, machines and workers will enable new interaction and collaboration, the institute said.
Australian tech firm Cohda Wireless has trialed its vehicle-to-pedestrian (V2P) technology on city streets for the first time.
The technology was originally designed to allow cars and motorcycles to avoid collisions by talking to each other.
In collaboration with Telstra and the South Australian Government, Cohda Wireless has conducted the first test of V2P technology over a mobile network in South Australia’s capital, Adelaide.
The system uses mobile technology to provide an early-collision warning to a driver and also alerts a pedestrian or cyclist via a smartphone application.
This innovation could become available in the 16 million smartphones in use in Australia and could potentially be extended to the two billion smartphones worldwide, the company said.
Cohda Wireless CEO Paul Gray said the trials highlighted the impact of vehicle-to-everything communications on community safety.
“Giving vehicles 360-degree situational awareness and sharing real-time driving information is the only way we can create safer roads for the future,” Gray said. “Cohda’s ongoing partnership with Telstra also demonstrates Cohda’s ability to deliver Cellular-V2X (C-V2X) solutions, an important part of the complete V2X system.”
The technology makes use of available 4G networks to allow riders, drivers and pedestrians who are further away to reliably receive necessary information.
Before a driver turns a blind corner the system will notify them of any pedestrian or cyclist crossing the adjacent street.
It was tested using other common scenarios, such as a car and a cyclist approaching a blind corner, a car reversing out of a driveway, and a car approaching a pedestrian crossing.
The trial was funded in part by the South Australian government’s AU$10 million Future Mobility Lab Fund to boost local testing, research and development of connected and autonomous vehicle technologies.
Cohda commands about 60 percent of the global vehicle-to-vehicle communication market.
It previously developed a “digital protective shield” system, which transmitted information such as vehicle types, speed, position and direction of travel between cars and motorcycles, at a rate of up to 10 times per second to ensure a high level of accuracy.
This service could be transmitted to any device within a several hundred-metre radius.
Telstra Chief Technology Officer Håkan Eriksson said the technology would make Australian roads safer, more efficient, and better-prepared for the future of autonomous vehicles.
“The most important outcome of V2X technology is the increased safety for road users, as the impact of human error can be minimized by helping vehicles communicate with each other and react to their surroundings,” he said. “This is the first time V2P technology has been trialled in Australia on a 4G network, and is an important step on the journey to fully-autonomous vehicles on Australian roads.”
South Australia has a history of involvement with autonomous car research and in 2015 held the first driverless car trials in the Southern Hemisphere.
It hosts a number of leading autonomous car companies including Cohda Wireless and its innovative V2X (Vehicle to everything) technology and RDM Group, which opened its Asia-Pacific headquarters in Adelaide earlier this year.
South Australia is also a leading driverless car research hub and earlier this week the University of Adelaide managed to improve artificial vision systems by studying dragonflies and other insects.
