Trimble Silvana/Anapala

GPS Receiver With Optimally Matched and Tuned Onboard Antenna

Manufacturer: Trimble
Trimble Silvana/Anapala

Integrating a GPS receiver and antenna in a tough electrical environment while wringing out every last dB of positioning performance is a complex RF design problem. Tight space constraints often place the GPS antenna near strong transmitters, noisy power supplies and fast microprocessors. Tracking down a source of interference in the system can take months. Getting it right often takes multiple expensive iterations and, in the end, engineers are frequently forced to compromise performance for time-to-market considerations.


Trimble has been integrating GPS receivers and antennas in all manner of devices for over 30 years now and can help you bring your product to market faster and with less aggravation. Trimble’s antenna companion modules (ACMs), including Silvana and Anapala, comprise a GPS receiver and a perfectly-matched antenna on an easily integrated module.


Compatible with Trimble’s Copernicus II, Condor and Panda families of GPS solutions, Silvana allows you to choose the best solution for your application. In addition to its onboard antenna, Silvana sports a connector for an external antenna. An antenna detection circuit automatically switches to the external antenna, when connected. With Silvana, one flexible solution serves both internal and external antenna applications


Like Silvana, Anapala supports multiple GPS solutions but relies on the integral matched antenna.
