https://www.electronics-lab.com/small-multi-band-gnss-receiver-1-cm-position-accuracy/
SkyTraq announced a 12- x 16-mm size PX1122R multi-band RTK receiver for centimeter-level accuracy GNSS positioning applications. The receiver works with all the four global navigation satellite systems using GPS L1/L2C, Galileo E1/E5b, GLONASS L1/L2, and Beidou B1I/B2I signals concurrently to maximize positioning availability even in difficult urban environments. Based on single-chip SoC design, PX1122R […]
A LoRaWAN Theft Recovery System for Stolen Bikes using a Low-Cost Dragino LGT-92
https://www.electronics-lab.com/lorawan-theft-recovery-system-stolen-bikes-using-low-cost-dragino-lgt-92/
Simon Kemper has published a guide for making use of the low-cost Dragino LGT-92 LoRaWAN asset tracking system to help track a bike when it’s stolen for easy recovery, while running for years on a single battery. Dragino LGT-92 is built for asset tracking across a LoRaWAN connection (a long-range low-power radio standard). The Dragino […]
Vintage VQB 71 Seven-Segment LED Displays Make GPS Clock Both Brilliant and Attractive.

Stephen Holdaway recently announced his project, a beautiful vintage VQB71 7-segment display based GPS Clock. Inspired by the fantastic appearance of the LEDs, Holdaway explains that the clock was built with a handful of vintage VQB 71 seven-segment LED displays and an u-box NEO-6M GPS module. “There are only so many applications for a 7-segment […]
Small, affordable gyroscope for navigating without GPS
https://www.electronics-lab.com/small-affordable-gyroscope-navigating-without-gps/
Researchers at the University of Michigan say they have developed a small, inexpensive, and highly accurate gyroscope that could help drones and autonomous cars stay on track without a GPS signal. The ultra-high-precision MEMS gyroscope – called the birdbath resonator gyroscope – is almost perfectly symmetrical, and made of nearly-pure glass. This, say the researchers, […]

Argos is a satellite-based system that collects, processes, and disseminates environmental data from fixed and mobile platforms worldwide. What makes Argos unique is the ability to geographically locate the source of the data anywhere on the Earth utilizing the Doppler effect. The Argos system itself comprises of six satellites, which follow polar orbits at an altitude of about 850km […]
GPS Clock using uLisp
https://www.electronics-lab.com/gps-clock-using-ulisp/
David Johnson-Davies writes about his experiments with interfacing a low-cost serial GPS module directly to uLisp, to create projects such as a GPS clock. He writes: I’ll also describe a GPS speedometer and odometer, and a simple navigator, in later posts. The module I used is the GP-20U7, a small GPS module available for under […]
