Jackson Labs Technologies Inc., a designer and manufacturer of GNSS, timing and frequency equipment, is releasing several new products with full support for the new and emerging Galileo satellite navigation system, as well as a free software retrofit to existing products that adds Galileo functionality. Jackson Labs’ low-phase-noise Rubidium GNSS disciplined oscillators (GNSDO). 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 U.S., and additional space vehicle launches are planned for later this year and next year that will significantly improve Galileo availability. Jackson Labs has upgraded its Mini-JLT GPSDO with an eighth-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. “A new era of global navigation system performance has arrived with the advent of enough usable Galileo space vehicles that are now allowing first positioning and timing operations,” said Jackson Labs President Said Jackson. “Galileo promises new technology and performance levels over the many decades-old GPS and GLONASS systems, and we are excited to lead the way with our new Galileo product line.” 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, the new Galileo-capable GNSS disciplined oscillator (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 a GNSS performance of down to -167 dBm. These new Galileo GNSDO’s provide 1 PPS 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 a typical holdover performance of up to, and better than 500 nanoseconds over 24 hours. Besides introducing the new Mini-JLT GNSS module, JLT also makes available concurrent Galileo reception via a free software update to existing customers of the JLT M12M replacement receiver, and the low-noise Rubidium product line.
