NovAtel have issued a bulletin to advise that there are updates to L-Band Tracking functionality on OEM 6 & OEM 7 receivers.
TerraStar satellite based correction services deliver precise GNSS corrections to the end user worldwide via L-Band beams from geostationary satellites. NovAtel GNSS receivers subscribed to TerraStar Correction Services access satellite clock and orbit corrections in these L-Band beams to compute real-time precise point positioning (PPP) solutions.
Summary of Issue:
Inmarsat, the communications satellite provider used to deliver TerraStar correction data, has provided notice that all TerraStar L-Band beam frequencies will move from the current location of 1539 MHz to 1545 MHz and higher in Q1 2018. The frequency change is required to avoid any potential impact from future mobile satellite services (MSS) that will share the lower portion of the current L-Band spectrum. This L-Band frequency change will affect all TerraStar L-Band beams and will impact all NovAtel receivers that use TerraStar Correction Services.
To confirm which beams cover your area of operation - please visit the TerraStar coverage map on the NovAtel website: https://www.novatel.com/products/terrastar-gnss-corrections/terrastar-coverage-map/
All V2 RT products with NovAtel OEM 6 cards running firmware older than 6.606. This includes:
- RT2002 & RT2002-250 V2
- RT3002 & RT3003 V2
- RT4002 & RT4003 V2
- Survey+ V2
All NovAtel receivers capable of L-Band tracking (and with an active or planned TerraStar subscription) must be updated to compatible firmware versions before the frequency change to ensure continuous operation of TerraStar services during and after the transition.
The attached Zip file contains a work instruction, and all appropriate information required to update your unit.
