●GPS Receiver Module - GT-525
Fast-Acquisition High-Sensitivity
20-Channel GPS Receiver Module
 |
The GT-525 is a compact all-in-one GPS module solution
intended for a broad range of Original Equipment Manufacturer (OEM) products, where fast and easy system integration and minimal development risk is required.
|
The GT-525 is a low-power star performers deliver top-notch accuracy, -159 dBm tracking, and track all satellites in view, setting the benchmark for real-time navigation, even through urban canyons and dense foliage. 200,000+ correlates—for fast and deep signal searches—into a new power-saving design, providing makers of portable and wireless devices with a low-power premium GPS solution.
The GT-525 supports SiRFInstantFixII technology, which satellite prediction technology greatly improves personal navigation device start-up times without the need for network connectivity. With one observation of each satellite, SiRFInstantFixII accurately predicts satellite positions for up to three days—removing the need to download satellite ephemeris data at subsequent start-ups— resulting in full navigation in as little as five seconds.
Both the LVTTL-level and RS232 signal interface are provided on the interface connector of the GT-525. Wide range power supply voltage form 3.2V to 5.5V is supported.

●GPS Dongle Series - UD-731
Fast Acquisition Enhanced Sensitivity
44 Channel GPS Dongle GPS Receiver
 |
The UD-731 is a compact all-in-one GPS receiver that
continuously tracks all satellites in view and provides
accurate satellite positioning data.
Its 44 parallel channels and 20000+ correlators provide fast satellite signal acquisition and short start-up time.
Acquisition sensitivity of -155dBm and tracking sensitivity of -158 dBm offer good performance even under difficult
environments.
|
The UD-731 is optimized for applications requiring good performance and low cost; it is suitable for a wide range
of handhelds, asset tracking, Notebook, PDA-centric personal navigation system, and vehicle navigation
products.
Data Logger(optional): Travel along with your GPS Dongle(UD-731), offers simultaneous use of real-time
GPS data logger.
