NovAtel, L-3 Interstate Electronics Partner on Civil RTK and SAASM Receiver Card

May 30, 2012By

NovAtel Inc. today announced the development of its OEM625S Selective Availability Anti-Spoofing Module (SAASM) GNSS receiver, a collaborative effort between NovAtel and L-3 Interstate Electronics Corporation (IEC). System integrators have come to rely on the centimeter-level positioning accuracy made possible with real-time kinematic (RTK) commercial GPS receivers. Many authorized defense customers rely on access to the Precise Positioning Service (PPS)... read more

Expert Advice: Thank Your Lucky Stars

March 1, 2012By

In my 20-plus years of involvement in the GPS/GNSS industry, nothing has come close to the LightSquared debate for technical and political complexity, nor for potential effects on nearly every high-precision GPS/GNSS user in the United States. The industry’s destiny is somewhat controlled by a federal agency that is not very knowledgeable about how, when, and where GPS is used — although I’m sure they’ve learned a lot in the last 14 months. read more

Innovation: Multipath Minimization Method

Mitigation Through Adaptive Filtering for Machine Automation Applications
Multipath is real and omnipresent, a detriment when GPS is used for positioning, navigation, and timing. The authors look at a technique to reduce multipath by using a pair of antennas on a moving vehicle together with a sophisticated mathematical model. This reduces the level of multipath on carrier-phase observations and thereby improves the accuracy of the vehicle’s position. read more
