"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.

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.

Washington View: Military GPS Receiver Advances Could Help Trim Satellite Costs

Advanced military receivers using the sort of modern multi-channel, multi-constellation capabilities already available commercially, could enable the Air Force to focus its anti-jam efforts on the ground, simplifying future GPS satellites and lowering their cost. Moreover, experts told Inside GNSS, the cutting-edge receivers could be deployed years before the anti-jam capability planned for the new GPS III satellites would be fully available. (more)

Thinking Aloud: Re-Baseline This!

What in other quarters is known as moving the goalposts has become a way of life for GPS. (more)

Listening for RF Noise: An Analysis of Pre-Despreading GNSS Interference Detection Techniques

Interference countermeasures are receiving increased attention in the GNSS community due, in part, to the advent of portable jamming modules. This article provides an overview on the vulnerability of GPS and Galileo receivers to continuous wave and chirp interference signals and compares the performance of interference-detection methods in terms of detection capability, detection latency, sensitivity to interference power, and computational and hardware complexity.
