GIS and the Future of Public Health
By Lurker,
The COVID-19 pandemic highlights the importance of GIS and spatial analysis to public health. We have seen a variety of analyses and use of spatial platforms to monitor and assess how to address the viral pandemic. However, what this crisis highlights are the needs and deficiencies in how GIS is used in public health and where GIS and public health will be in the future.
Trends in public health and GIS started before the COVID-19 pandemic, although the current crisis may catalyze some

NOAA report supports GNSS-RO for weather and space forecasts
By Lurker,
On June 26, the U.S. National Oceanic and Atmospheric Administration (NOAA) released the summary of the results of Commercial Weather Data Pilot (CWDP) Round 2. View the summary here.
In Round 2, NOAA evaluated GNSS radio occultation data from two U.S. commercial space companies: GeoOptics and Spire. NOAA concludes that, based on the results of CWDP Round 2, the commercial sector is able to provide radio occultation data that can support NOAA’s operational products and services.

Septentrio launches mosaic-T GNSS receiver
By Lurker,
Septentrio has launched the mosaic-T GPS/GNSS receiver module, built specifically for resilient and precise time and frequency synchronization under challenging conditions.
According to the company, its multi-frequency, multi-constellation GNSS technology — together with AIM+ Advanced Interference Mitigation algorithms — allows mosaic-T to achieve maximal availability even in the presence of GNSS jamming or spoofing. This compact surface-mount module is designed for automated assembly and h
SBG Systems advances GNSS/INS with 3rd-generation Ellipse
By Lurker,
SBG Systems has announced the third generation of its Ellipse series of miniature inertial sensors. The renewed product line benefits from a 64-bit architecture, allowing high precision signal processing.
All of the INS/GNSS devices now embed a dual-frequency, quad constellations GNSS receiver for centimetric position and higher orientation accuracy.
SBG Systems manufactures miniature high-accuracy inertial navigation systems with inertial measurement unit (IMU) design, calibration and

GPS is an incredible piece of modern technology. Not only does it allow for locating objects precisely anywhere on the planet, but it also enables the turn-by-turn directions we take for granted these days — all without needing anything more than a radio receiver and some software to decode the signals constantly being sent down from space. [Chris] took that last bit bit as somewhat of a challenge and set off to write a software-defined GPS receiver from the ground up. As GPS started as a military technology, the level of precision needed for things like turn-by-turn navigation wasn’t always available to civilians. The “coarse” positioning is only capable of accuracy within a few hundred meters, so this legacy capability is the first thing that [Chris] tackles here. It is pretty fast, though, with the system able to resolve a location in 24 seconds from cold start and then displaying its information in a browser window. Everything in this build is done in Python as well, meaning that it’s a great starting point for investigating how GPS works and for building other projects from there. The other thing that makes this project accessible is that the only other hardware needed besides a computer that runs Python is an RTL-SDR dongle. These inexpensive TV dongles ushered in a software-defined radio revolution about a decade ago when it was found that they could receive a wide array of radio signals beyond just TV. source: Hackaday and GitHub - chrisdoble/gps-receiver
