The Global Positioning Systems Wing will be hosting on February 12 an Interface Control Working Group (ICWG) teleconference meeting for the document IS-GPS-200E (NAVSTAR GPS Space Segment/Navigation User Interfaces). The meeting will address comments received on L2 Phase Relationships after the...More>>

Precision technology company InterSense, Inc. has unveiled the NavChip OEM Developer’s Kit at the Institute of Navigation’s 2009 GNSS show. The kit includes a pre-release engineering sample of InterSense’s NavChip, which the company expects to become the industry’s first commercial inertial...More>>

The U.S. Space Exploration Policy, unveiled in 2004, seeks to extend human exploration with missions to the moon, Mars, and beyond. Implementing this ambitious Project Constellation (including a lunar outpost and trips to Mars) requires establishing a cost-effective, synergistic communications and...More>>

Who says space exploration is only for nations or corporations? This summer, students from Oklahoma State University's Radiation Physics Laboratory built and launched a cosmic radiation detector with GPS, which touched the edge of outer space.More>>

The phased transition of the 22-year-old Legacy GPS Master Control Station (MCS) to the Architecture Evolution Plan (AEP) control segment, which became operational in September 2007, constituted a multi-year cooperative effort to achieve a seamless navigation service transition to GPS users.More>>

Modeling and simulation, two separate but related activities conducted prior to flight tests of high-performance military navigation systems, can reduce costs, shorten timelines, and remove some uncontrollable variables from the process, to deliver more accurate, verifiable results.More>>

A solid-state GPS navigation system enables widespread use of GPS in smaller manned and unmanned aircraft, achieving the accuracy and robustness typically associated with larger, higher cost systems. The NAV420's sensors, data-acquisition elements, and Kalman-filter-based algorithm allow smaller...More>>

To initially acquire the GPS signals, a receiver also would have to search quickly through the much larger range of possible Doppler shifts and code delays than those experienced by a terrestrial receiver.More>>

A recent simulated test of military UAVs demonstrated one more envisioned GPS role in military operations. As part of the J-UCAS program, Northrop Grumman performed a test of simulated, simultaneous control of four X-47B UAVs on September 28, 2005, at the Naval Air Warfare Center Weapons Division...More>>

GPS dropsondes released into the Katrina's eyewall tracked and predicted wind strength, speed, and direction.More>>
