Jackson Labs Technologies, a designer and manufacturer of cutting-edge GNSS, timing and frequency equipment has announced a range of new products with full support for the new and emerging Galileo Satellite Navigation System, as well as a free software retrofit to existing products adding Galileo functionality.
The European Galileo satellite navigation system has now become a reality with recent launches and commissioning of Galileo satellites. Three to four Galileo satellites can now typically be tracked on average in the continental US. Additional space vehicle launches are planned for later this year and next year to significantly improve Galileo availability. JLT has upgraded the popular Mini-JLT GPSDO with an 8th generation GNSS NEO-M8T Timing receiver from u-blox that allows receiving Galileo signals as well as concurrent GPS, Glonass, BeiDou, and QZSS signals. Users can choose to operate a single GNSS system, or multiple concurrent GNSS systems for redundancy. Concurrent operation aids performance by allowing reception of up to 72 GNSS satellites in challenged reception areas such as in urban canyons, under foliage, indoors, or close to the earth's poles etc.
The Galileo GNSS promises significant improvements in timing and frequency performance due to improved on-board Hydrogen Maser Atomic references (Cesium and Rubidium references are used in GPS and Glonass satellites) and other system improvements. In stationary timing mode, this new Galileo-capable GNSDO products will operate with as little as one single satellite in-view, and can use additional satellites to improve timing stability and accuracy via an over-determined timing solution for oscillator disciplining. Indoor tracking is possible with an unmatched GNSS performance of down to -167 dBm.
The new Galileo GNSDO's provide 1PPS timing, Position and Navigation (PNT) data, as well as highly-stable and accurate 10 MHz reference outputs. The M12M Replacement Receiver also provides a user-adjustable timing/frequency output with 1 Hz to > 10 MHz adjustment range, while the Low Noise Rubidium GNSDO can provide an industry-leading typical holdover performance of up to, and better than 500 ns over 24 hours.
Besides introducing these new Mini-JLT GNSS module, Jackson Labs Technologies also makes available concurrent Galileo reception via a free software update to existing customers of their M12M Replacement Receiver, and the Low Noise Rubidium product line.
