This is a demonstration of my GPS receiver that I will be using for my UAV project.
A slightly abbreviated post today â€“ weâ€™ve just driven 380 miles to Phoenix from LA for Intel ISEF, where Ebenâ€™s talking tomorrow, and weâ€™re ready to drop. But I was mailed this amazing piece of work this morning, and it really deserves your attention.

The authors test three mass-market design drivers on a chip developed expressly for a new role as a combined GPS and Galileo consumer receiver: the time-to-first-fix for different C/N0, for hot, warm, and cold start, and for different constellation
You don't send data through a GPS system, the GPS satellite network operated by the Air Force just sends out signals that are used by a GPS receiver to calculate its position.â€ť Recently, Aireon completed the qualification testing for its receiver payload.

Here are the pictures, and the story they tell. Test data coincident with the GLONASS ephemeris disruption of April 1 and 2 showing conclusively how a GPS/GLONASS/QZSS/BEIDOU receiver survives the complete disruption of one of the constellations.
L2C is the second civilian GPS signal, and when combined in a dual-frequency receiver with the legacy L1 C/A civil signal, enables ionospheric correction that will improve accuracy. The signal broadcasts at a higher effective power than L1 C/A, which
This is a step beyond regular GPS services, which act as more of a one-way system by only communicating with a receiver. â€śWhen you use GPS, all you know is where you are,â€ť said Thoma. â€śYou need a second system to be able to transmit that ...
Nike offers two types of GPS devices you can use for speed training: the Nike+ SportWatch that contains a GPS receiver and Nike+ GPS App, an application that you can download into your iPhone. Either can provide you with detailed information to improve ...
Coincidentally, during that 11-hour period, the mass-market chip company Broadcom was conducting multi-constellation receiver tests in Asia. Frank van Diggelen, Broadcomâ€™s chief GNSS scientist and vice president says, â€śWe have definitive data to show ...
