GPS systems getting a major shot of adrenaline!

Military GPS receiver market approaches $3B as electronic warfare surge has prioritized the need to deal with sophisticated electronic jamming and spoofing.

GPS receivers are being re-jigged to integrate M-Code > a highly secure military GPS signal designed to operate reliably in heavily contested electronic environments and deliver anti-jamming protection.

Rather than just receiving signals, modern military GPS receivers are increasingly expected to actively identify spoofed data streams and coordinate with electronic countermeasures to suppress adversarial transmitters. https://satnews.com/2026/06/22/navigating-contested-battlespaces-military-gps-receiver-market-approaches-3-billion-amid-electronic-warfare-surge/

"There’s More To Global Positioning Than Just GPS" by @hackaday - US GPS🛰️ started it but isn't the only public global navigation system now. Initially planned for military use, GPS was first to open to public use (after KAL Flight 007✈️ was shot down in 1983) and then others followed. Sophisticated multi-network receivers now improve #Positioning #Navigation #Timing #PNT resolution by combining data from all satellites in view. https://hackaday.com/2026/05/07/theres-more-to-global-positioning-than-just-gps/ #GNSS #GPS #Galileo #Glonass #Beidou #space

"The GPS III Rollout Is Almost Complete, But What Is It?" by @hackaday / @tomnardi - New 3rd generation of #GPS satellites transmit with higher power and use new protocols to improve signal acquisition and resist interference. It's backward compatible with older GPS receivers (i.e. phones, cars, aircraft) but much improved for new receivers designed for GPS III. https://hackaday.com/2026/04/28/the-gps-iii-rollout-is-almost-complete-but-what-is-it/ #GNSS #positioning #navigation #timing #PNT #satellite #space

"Laser Ranging Makes GPS Satellites More Accurate" by @hackaday - Laser retroreflector on newest #GPS satellite is the first of what will be on all upcoming GPS satellites. Similar reflectors left on the Moon by Apollo astronauts allow scientists to measure distance to the Moon to the millimeter. Same use for GPS satellites will reduce error in their estimated trajectory, and improve #positioning, #navigation & #timing #PNT derived from them. https://hackaday.com/2026/03/29/laser-ranging-makes-gps-satellites-more-accurate/ #GNSS #satellite #space

#GPS / #GNSS #trivia:

The least accurate data from a GPS or other GNSS receiver is altitude.

The most accurate is time, followed by speed.

"GPS And Its Little Modules" by @hackaday - GPS receiver electronic modules currently are actually multi-GNSS system receivers for GPS🇺🇸, Galileo🇪🇺, Glonass🇷🇺, BeiDou🇨🇳 and other countries' emerging systems. Usually your circuits will ingest pulse-per-second or faster data via UART or I2C interface. https://hackaday.com/2025/09/08/gps-and-its-little-modules/ #GPS #GNSS #electronics #space #positioning #navigation #timing #PNT #Maker #DIY #tech

I ran across a free HarvardX course (well, free to audit if you don't want a "verified certificate") covering the history of navigation. Looks interesting for anyone wanting to learn what came before today's #PNT, #GPS, #GNSS, etc...
