A new method brings together advantages of real-time kinematic (RTK) and precise point positioning (PPP) in a technique that does not require local reference stations, while still providing the the high productivity and accuracy of RTK systems with the extended coverage area of solutions based on gl...

The stability of a received GPS signal determines how well the receiver can track the signal and the accuracy of the positioning results it provides. While the satellites use a very stable oscillator and modulation system to generate their signals, just how stable are the resulting phase-modulated c...

Read More →Just for the record: what is reported in “Detecting False Signals With Automatic Gain Control” (April GPS World) is what we introduced a long time ago and is reflected in one of our videos, and implemented in all of our GNSS receivers. AGC information is one of the four ways, and the least signi...

Augmented reality delivers two important military capabilities to the warfighter: situational awareness and precision piloting capabilities, both key to survival on the battlefield. Look-ahead drive-to-position, based on accurate GPS positions, extends the importance of GPS to high-speed operation o...
Read More →By Art Kalinski Few of us fully appreciate the significance of the Qur’an burning in Afghanistan by our troops several months ago. The best analogy I can think of is burning of an American flag. As any Boy Scout can tell you, the proper way to dispose of a worn American flag is to burn it in a d...
