SkyTraq S1722R8 - GPS module

Description

Global navigation satellite system GPS receiver module. It contains the SkyTraq Venus 8 positioning motor inside, characterized by high sensitivity and low energy consumption. The excellent cold start sensitivity of -148 dBm allows for self-acquisition, tracking and positioning in a difficult environment with a weak signal. Receiver tracking sensitivity of -165dBm enables continuous position coverage in almost all application environments. The module works with a passive and active antenna.
