Like all previous Novella tracking products the new compact tracking receivers have been designed to track and measure beacons of all known commercial and military satellites.
The combination of tried and tested PLL techniques, the latest developments in integrated RF technology and the unique beacon search and anti-sideband (ASB) circuitry allows these receivers to re-acquire lock in all circumstances making them ideal for tracking highly inclined orbit satellites where Döppler shift causes lower quality Trackers to fail.
A low threshold of 43dBHz, fast re-acquisition of less than 1s and high linearity make Novella's receivers the preferred choice for small antenna field deployable stations (C,X , Ku and Ka Band) requiring fast automatic satellite acquisition.
They are now the product of choice to track NATO/Skynet/DSCS BPSK modulated beacons and the ideal solution for SNG vehicles requiring fast automatic antenna deployment and satellite acquisition.
Novella receivers are available with interface at 70/140MHz, L, S, C, X, Ku or Ka-band. They are also available in a variety of multiband packages, namely C, X and Ku-bands.
