ABC Assessment Data Shows Wide Impacts to Some GPS Receivers

Test results from the long-running Adjacent Band Compatibility (ABC) Assessment show interference from wireless signals in nearby bands could negatively impact GPS receivers kilometers away from Long-Term Evolution (LTE) ground stations and render some more closely located GPS receivers useless.

Fall Delivery Expected for GPS OCX Block O

A Raytheon executive said that the company expects to deliver the Block O Launch and Checkout System to the U.S. Air Force this fall as part of the GPS Next Generation Operational Control System (OCX).  

In addition, the company completed a baseline procedure to recertify the troubled OCX program, which was approved by the U.S. Air Force, at the end of March, said Bill Sullivan, Raytheon vice president and program manager for GPS OCX, at the recent 33rd annual Space Symposium meeting in Colorado Springs, Colorado.

Europe's GNSS Receiver Standard Nears Approval

European Union (EU) member countries are close to adopting a standard for satellite navigation receivers.

The proposed standard covers Satellite Earth Stations and Systems (SESS) as well as GNSS receivers operating in the bands 1164 MHz to 1300 MHz and 1559 MHz to 1610 MHz. Receivers must be able to withstand interference from adjacent bands at the listed levels.

Japan’s Second Michibiki Satellite Will Boost QZSS

Officials at the Tsukuba Space Center of the Japan Aerospace Exploration Agency (JAXA) announced that the second satellite in the Japanese Quasi-Zenith Satellite System (QZSS) is scheduled for launch in June.

Designed to boost the accuracy and reception of the existing GPS system for Japan, a new version of a satellite that will orbit directly over the Japanese archipelago was unveiled last week. It will improve the existing GPS and provide a better positioning reading for the people in Japan.

Skyworks Launches Low-Power LNA for GNSS Radio Receiver Applications

Skyworks Solutions of Woburn, Massachusetts, has launched the SKY65623-682LF low-noise amplifier (LNA) for applications including wearables, asset trackers, navigation devices, and action cameras.

The SKY65623-682LF is a Microwave Monolithic Integrated Circuit (MMIC) front-end LNA designed for GNSS radio receiver applications. The device is designed to provide low current consumption (1mA @ 1.8V supply), optimal gain, and a superior noise figure (NF). Output matching components are embedded inside the device. Only one external input matching inductor is required.
