GPS sensor

The CW46 GPS sensor is an integrated module that includes the CW25 GPS receiver, DC/DC converter, RS232, RS422 and USB interface options and active GPS antenna, all housed in a weatherproof (IP67-rated) enclosure.

The receiver has been designed to acquire and track satellites in weak signal areas such as under dense foliage, severe urban canyons and inside buildings. The CW46 can acquire satellites at signal levels down to -155 dBm. It can also autonomously acquire satellites at signal levels as low as -143 dBm.

The device uses the CW25-TIM GPS receiver inside, allowing the CW46 to act as a timing module capable of outputting a GPS disciplined frequency up to 10 MHz that can achieve full PRC MTIE performance in good signal areas.

The CW46 can also continue to provide synchronisation in weak signal areas, including inside buildings.
