    Nestwave white paper considers power consumption for IoT devices

    Nestwave logoNestwave has released a white paper that considers the challenges associated with integrating accurate geolocation into compact, battery-powered, low-cost internet of things (IoT) nodes.

    The technical paper “Minimizing Power Budgets to Enable Geolocation on Every IoT Device” is targeted at engineers and developers looking to add accurate positioning functionality to IoT technologies where power requirements must be kept to an absolute minimum.

    Topics covered include:

    • why conventional tracking architectures are not suitable for many IoT implementations
    • the importance of factors such as time-to-first-fix (TTFF)
    • the number of fixes and levels of integration in determining power consumption.

    The paper introduces new ways of handling positioning signal acquisition, ranging and tracking, and proposes solutions that eliminate the need for a separate GNSS-integrated circuit and that offload energy-intensive computation to the cloud.

    “Tracking will be an important element in the evolution of the IoT, which means making accurate geolocation viable for every single IoT node is absolutely critical,” said Ambroise Popper, Nestwave CEO. “This paper explains why traditional solutions are too power-hungry, too large and too expensive to meet the energy, form factor and cost constraints of most IoT devices and introduces solutions for addressing the challenge.”

    Rx Networks adds StarCourse extended ephemeris services

    Rx Networks has added a new extended ephemeris service called StarCourse.

    According to the company, real-time ephemeris services provide GNSS chipsets in connected mobile devices a headstart in determining position accurately and quickly. For devices with limited connectivity, typical extended ephemeris solutions have provided a headstart with 7-14 days of ephemeris data.

    With the evolution of the internet of things (IoT), low power consumption and a limiting of connection time are essential for extending the usable life of a device. This creates a challenge for IoT vendors seeking an extended ephemeris offering that can minimize onboard resource usage without compromising accuracy.

    The new StarCourse service provides a 50% reduction in RAM requirements, 90% reduction in CPU cycles, and ephemeris accuracy exceeding that of previous market offerings. This empowers Rx Networks customers to extend the usable life of their products while delivering an excellent positioning experience, the company said. Full data customization is offered to StarCourse subscribers, allowing them to create optimal solutions for their needs.

    StarCourse enables autonomous positioning on a wide array of connected GNSS IoT devices, including asset tracking, wearables, in-dash navigation and mobile devices. For situations where accuracy is paramount, StarCourse Premium provides ultra-precise predicted ephemeris for the first 24 hours.

    “GNSS assistance services are essential to solving the spatial intelligence requirements of the booming IoT world,” said Chris Perriam, product owner at Rx Networks. “StarCourse endeavours to quickly enlighten all connected devices with location.”

    Rx Networks provides location information to strengthen the connection between people, devices and businesses by improving the GNSS experience and creating enhanced opportunities for next-generation products and services.
