GSS9000a-Spirent-O

Spirent Federal Systems, a U.S. provider of positioning, navigation and timing test solutions to the government and its contractors, announces that its GSS9000 RF constellation simulator has been reviewed and granted security approval by the GPS Directorate. Higher dynamic simulations with more accuracy and fidelity are enabled by 1000-Hz (1 ms) System Iteration Rate — a four-fold increase over Spirent’s current GSS8000 product — zero inter-channel bias... read more

Rockwell Tracks Galileo Signal with Secure Software Receiver

September 15, 2014By

Rockwell Collins has successfully received and tracked a Galileo satellite signal using a prototype GNSS receiver designed for secure military use. In 2013, Rockwell Collins received a $2 million contract from the Air Force Research Laboratory (AFRL) and the GPS Directorate to develop and demonstrate a Secure Software Defined Radio (S-SDR) GNSS receiver capability. By using multiple available satellite signals, improved and more... read more

Galileo Provides Update on FOC Anomaly, GLONASS a No Show

September 10, 2014By

Experts representing the Galileo Program provided a frank and open update on how it is addressing the problem of the first two full operational capability (FOC) satellites being delivered to the wrong orbit. The presentation was part of the panel discussion “Status of GPS, GLONASS, Galileo, BeiDou, and QZSS” at ION GNSS+ Wednesday morning. No one from Rocosmos attended to... read more

Using GPS Multipath for Snow-Depth Estimation
In this month’s column, we look at a technique that uses interference fringes generated by signals arriving at an antenna directly from GPS satellites and those reflected by snow surrounding the antenna to measure its depth and how it varies over time. GPS for measuring snow depth; who would have thought? read more

Multi-Constellation. Dual-Frequency. Single-Chip.

September 1, 2014By
NAPA-OpeningFigure

This integrated circuit supports simultaneous reception and processing of the GPS L1/L5, Galileo E1/E5a, and GLONASS G1 signals with 40 tracking channels. The dual-band analog RF front-end is integrated on the same mixed-signal chip as the baseband hardware, including an embedded processor to close the tracking loops: overall, a compact, low-power, and low-cost solution. read more
