GR-201 Marine GPS Locator
GR-201 is an outstanding high sensitivity Marine GPS receiver. It is the latest GPS product innovation in combining GPS receiver technology and mini-antenna in a Plug-Navigate-Location concept from SAN JOSE NAVIGATION, INC.
GR-201 receives broadcast signals from the Low Orbit Global Positioning System (GPS), a satellite-based transmitter which emits ranging/satellite information/high precision time signals that the GR-201 receiver can use to determine positions and time. It also has high sensitivity for weak signal operation without compromising accuracy.
