GAO Watchdog Report: Military Space Acquisition Process, Including GPS, Still Fractured, Costly
[SIGNALS exclusive] A new report from the Government Accountability Office (GAO) outlines how, after decades of debate, the Department of Defense (DoD) system for buying and integrating space systems remains complex and fractured - causing delays, cost overruns, and cancellations among the department's many space programs, including GPS.

High-precision GNSS technology for the mass market
u-blox addresses the demand for lower priced high-precision technology ideal for UAVs and guidance robotics.



The demand for lower priced high precision technology is growing rapidly, as evident in the areas of precision agriculture, UAVs, and robotic lawnmowers. However, due to size, power, and cost restrictions, existing high precision solutions have been unable to meet the demands of these markets.
Surprise GPS Receiver Tests Involving Ligado Spectrum Effort  
A government agency is poised to release a surprise test plan for GPS receivers that appears to incorporate a highly controversial yardstick for determining when a service in adjacent frequencies interferes with GPS signal. (more)

"Fundamentals of GPS Threats": Discover how the growing threats to satellite navigation signals can impact your critical systems, and what you can do about it - White Paper
Satellite navigation signals from space are precariously weak and can easily be blocked, damaged, or compromised by a growing array of threats - including solar activity, man-made interference, malicious faking of GPS signals, and the manipulation of position and timing information. As we come to rely more and more on GNSS signals and data across a wide range of industries, understanding and mitigating against these threats will become a critical risk management activity for manufacturers, systems and applications providers, and end-users.

Extreme Georeferencing - Mapping the Moon [Paper]
Carnegie Mellon University (CMU) used visual, inertial and LiDAR sensors to create a surveying instrument that could eventually be used to model collapsed caves on the Moon, Mars and beyond. The CMU instrument applies geo-referencing technology, including KVH inertial sensors, to create high resolution 3D modeling of planetary caves. Precision mobile mapping will be critical to finding these caves, potential sites for extra-planetary colonies as well as environments for extra-terrestrial life.
First Results - GLONASS CDMA L3 Ambiguity Resolution
Researchers in Australia present their first results of GLONASS CDMA L3 ambiguity resolution. Based on the observations from two GLONASS satellites that were collected at Curtin University, this article assesses the performance of geometry-free and geometry-fixed L3 ambiguity resolution methods and compares the outcomes with their GPS L5 counterparts..
