Caution
Read before you start to use:
Global position system (GPS) is obtained by American Ministry of National Defense, and they got the full responsibility about the
preciseness and the maintenance. Any changes may cause the capacity and preciseness of GPS differed.
If you use this device inside of buildings, tunnels, or any huge objects beside you, the GPS signals might be cut-off or disturbed. Please
do not consider that the receiver is malfunction.
The receiver operating temperature is located between – 20°C and + 60°C.
1. Introduction
The GPS USB Dongle Receiver is a total solution of GPS receiver with Venus 621 ;65 channels all-in-view tracking technology.
This GPS USB Dongle Receiver can communicate with other electronic devices by USB interface.
The GPS USB Dongle Receiver is designed as an ultra low power consumption device, and high position accuracy. It will update the
satellite position every second. This GPS USB Dongle Receiver auto-locating feature is capable of automatically determining a navigation
solution without intervention. However, acquisition performance could be interfered and do cold start if the receiver were initialized with
occurrence of the following events:
1) First in use
2) The GPS receiver is not in use for more than 3 months or transportation over distances further than 500 kilometers.
2. Features and Functions
1) Venus 621 simultaneous time-frequency search bins. Signal detection better than -160dBm
2) Cold start < 30 seconds at –147dBm
3) Hot start < 1sec. under open sky.
4) 5m CEP accuracy.
5) Signal reacquisition 1 sec.
6 Acquire and track 65 satellites simultaneously
7) USB Version 1.1/2.0, 4dBm output level Up to 10m of operation
8) Data tag (start, stop point): This means you can set the G730 to log in different time or distance intervals. This function is to be used
from the Photo Tagger software.
