MG-550
Mainnav's MG-550 GPS Receiver provides you various applications such as car navigation, marine navigation, mapping, surveying, security, agriculture and so on. It communicates with device (such as PocketPC or notebook) via compatible dual-channel through RS-232 or TTL and saves satellite data by built–in backup memory. Low power consumption technology enables MG-550 and your device to save more operating power.
Furthermore, MG-550 can track up to 20 satellites at a time, re-acquire satellite signals in 100ms and update position data every second. Trickle-Power allows the unit to operate a fraction of the time, and Push-to-Fix permits user to have a quicker position fix even though the receiver stays off.
