Image: SparkFun

SparkFun Electronics has released the NEO-F10N GNSS L1/L5 Breakout board. This GNSS breakout board features the u-blox NEO-F10N module and a dual-band L1/L5 configuration designed to add precision to GNSS projects operating in urban and rural environments. Additionally, the L5 signal falls within a protected frequency band, which reduces RF interference on the incoming signal.

This breakout supports the concurrent reception of three GNSS constellations: GPS, Galileo, and BeiDou. The proprietary dual-band multipath mitigation technology from the u-blox F10 allows the module to choose the best signals from both bands to achieve a significantly better position accuracy in challenging urban environments than with the L1 band alone.

It has an integrated rechargeable battery that powers the RTC on the NEO-F10N, which reduces the time-to-first fix from cold to hot starts. The battery also maintains RTC and GNSS orbit data without external power to offer uninterrupted performance.

u-blox-based GPS products are configurable using u-center. This offers users extensive customization options such as baud rates, update rates, spoofing detection and more.

CHCNAV unveils handheld SLAM laser scanner

Image: CHCNAV

CHC Navigation (CHCNAV) has released the RS10 handheld SLAM lidar laser scanner integrated with a full real-time kinematics (RTK) GNSS receiver. Designed to improve efficiency across a wide range of mapping and surveying applications, the RS10 seeks to provide professionals with a versatile, all-in-one tool for capturing 3D geospatial data in both outdoor and indoor environments.

The device integrates a GNSS smart antenna for RTK positioning accuracy even in challenging environments.

u-blox launches GNSS platform for urban environments

Image: u-blox

u-blox has introduced the F10 dual-band GNSS platform. It combines L1 and L5 bands to offer enhanced multipath resistance and meter-level positioning accuracy. The platform caters to urban mobility applications, such as aftermarket telematics and micro-mobility.

Applications that use GNSS receivers for accurate positioning are on the rise. Yet, current receivers do not fully perform in urban areas. Accurate and reliable positioning in dense urban environments — where buildings or tree foliage can reflect satellite signals — requires GNSS receivers to mitigate multipath effects. The L5 band’s resilience to these effects aims to improve positioning accuracy. Combined with the well-established L1 band, an L1/L5 dual-band GNSS receiver can deliver a less than 2 m positioning accuracy (CEP50), against about 4 m with the L1 band only. The u-blox team has conducted driving tests in several urban areas and reported significant improvement over GNSS L1 receivers.

The F10’s firmware algorithm prioritizes L5 band signals in weak signal environments to provide reliable positioning accuracy, even when paired with small antennas. The platform is also equipped with protection-level technology that provides a real-time positioning accuracy estimate.

When a cellular modem is extremely close to a GNSS receiver, it can interfere with the receiver’s reception. Some F10 module models, such as NEO-F10N, MAX-F10S, and MIA-F10Q, are equipped with a robust RF circuit that allows the GNSS and the cellular modem to operate without interference.

The u-blox F10 platform is pin-to-pin compatible with the previous u-blox M10 generation for easy migration. It also supports u-blox AssistNow, which offers real-time online A-GNSS service with global availability to reduce GNSS time-to-first fix and power consumption.

The u-blox EVK-F101 evaluation kit will be available in April 2024.

u-blox, CTT collaborate on penguin conservation effort

Image: u-blox

u-blox has partnered with Cellular Tracking Technologies (CTT), a specialist in wildlife telemetry and Internet of Things (IoT) solutions, in an initiative aimed at conserving Antarctic wildlife.

The collaboration has introduced a cloud-based positioning solution to monitor the activities of Adélie penguins in Ross Island, Antarctica. The venture began when Point Blue, an American wildlife conservation organization, reached out to CTT to create a tracking mechanism that could study the movements of young Adélie penguins. These birds are among the five penguin species inhabiting Antarctica and are considered crucial for environmental studies due to their sensitivity to ecological shifts caused by climate change and human activities, such as commercial fishing.

Due to the challenging conditions in Antarctica, tracking penguins required a device that was lightweight, non-intrusive, energy-efficient, and cost-effective in terms of data transmission. This was particularly important given the small size of the penguins, their rapid movement, and their extended underwater dives.

u-blox provided its CloudLocate positioning service to meet these stringent requirements, which led to the development of CTT’s Penguin Iridium GNSS tracker. The tracker is fixed to the penguins’ backs and uses one of u-blox’s compact GNSS modules. The CloudLocate service processes the positioning calculation in the cloud rather than on the device to save energy and enable prolonged monitoring periods without the need for frequent device replacements.

The tracker operates by sending a concise 50 B message, which captures essential location data during the brief moments when a penguin surfaces for air. This level of efficiency is critical in minimizing the costs associated with satellite connectivity, which is often prohibitively expensive in such remote regions.

This partnership marks an advancement in wildlife conservation technology by allowing for non-invasive, continuous monitoring of Adélie penguins and providing vital data for assessing the impacts of environmental changes. CTT aims to extend this tracking solution to a wider range of wildlife research and conservation projects to demonstrate the potential for technological innovation to contribute significantly to ecological preservation efforts.

Savvy navvy launches AIS update

Image: savvy navvy

savvy navvy has released Over the Horizon (OHA) automatic identification systems (AIS) in its latest mobile application update. OHA uses a phone’s internet connection to stream other vessels’ locations in real-time directly to the app to improve safety on the water.

Traditional AIS received from the transceiver on the boat has a range of a few miles, whereas OHA is designed to show vessels further afield. While OHA does require an internet connection, users do not need additional hardware to see information on vessel movements.

“Not all boaters have AIS hardware on their boats,” said says Jelte Liebrand, founder and CEO of savvy navvy. “A recent study found that depending on the vessel type, 30% of boaters, and in some cases even as much as 75%, do not own AIS transceivers. But all these boaters could benefit from OHA AIS to be able to see what’s around them and stay safe.”

OHA AIS allows savvy navvy users to see vessels directly on the chart with small and large vessel crafts defined by different colors. Users can also check how crowded the anchorage might be — either from onboard or while planning routes at home.

The savvy navvy app highlights when no position has been received for more than 30 seconds, which marks the positional variance area around each vessel and allows users to be extra vigilant when navigating.

Available on Android, IOS, PC and Mac, the savvy navvy app can be used on multiple devices and is available in both free and “premium” options with enhanced access and functionalities.

In the Field: Help survey monuments complement GNSS

GNSS users who appreciate that physical monuments can provide verification of GNSS observations can do four things to preserve those monuments and make them more accessible. References below are to U.S. national agencies, but most countries have equivalent agencies.
1. Install a valve box over each buried control point recovered or set, whether the point is for boundary or geodetic surveying. Include National Geodetic Survey (NGS) deep-rod marks that have a buried logo cap.
2. Advocate with the Secretary of the Interior and United States Geological Survey (USGS) director that USGS scan its paper geodetic data sheets and post the scanned pdf files online.
3. Adopt the geodetic marks in your area. Visit them. Keep them free of brush or other blockages. Maintain descriptions and photos up to date by submitting recovery notes to NGS as needed. Participate in the NGS GPS on Benchmarks program.
4. Consider recovering all the marks in an NGS level line. Alternatively, all the USGS marks in a 15’ quadrangle, the geographic unit USGS uses to publish its geodetic data.
Figure 2: Example of USGS vertical data published by 15’ quadrangle.

Regarding the first of these actions, a valve box is a utility standard. It identifies to non-surveyors that there is something under the box to which one should pay attention, thus increasing the mark’s chances of survival.

The box lid is generally obvious, eliminating or at least reducing the search time for surveyors, who only need to walk up to the box.

It replaces the soil that previously covered the mark, reducing excavation time. A surveyor only needs to open the lid and brush off the mark. Rectangular and round boxes in several sizes are available to accommodate different-sized monuments. While the time and materials to install a box may be an overhead cost to your company, it is well worth the investment.

Regarding the second of these actions, the positions and heights published for most USGS control marks are based on superseded datums. However, that old data can be useful for evaluating trends. The marks are usually stable and can be reused in new projects.

While NGS has observed some of these marks and published datasheets for them, they are by far the minority of all the USGS marks in the country.

There are thousands of these sheets, 50 shelf-feet of them, organized by 15’ quad. Some sheets, mainly in the East, have been scanned and put online by various state agencies or utility companies. The USGS Rolla office has scanned most of the eastern states but has not posted the files online.

Generally, a request for USGS geodetic data turns into a request for paper sheets, such as those shown in Figure 2, to be scanned and emailed. Putting them online would preserve this record of what it took to survey and map our country, allowing the marks to be tied into new control surveys.
