Q:What do you need to test for GPS?
As a high-tech product, GPS has a very complex technical parameters.

All of our products are in Shenzhen channel 16 channel, multi-channel parallel GPS receiver, including the advantages of rapid cold start and initialization of satellite information, but also in the forest area can have a better reception. General 12 channel receiver does not require an external antenna, unless you are in a bad environment conditions such as closed space, such as the cabin, the car. 2 the sensitivity of the GPS satellite signal to the ground has been very weak, as well as ground wireless communication clutter interference. The lowest traceable signal strength of the GPS receiver determines how much useful signal is received. A GPS receiver with a lower minimum tracking signal strength has a higher sensitivity, and can receive more available satellites under bad conditions
