Specification :

GlobalTop Technology offers a wide variety of firmware customizations based on customer’ s request and applications. We have an experience firmware and software development team dedicated to satisfy the needs of different applications. Below are some of the ready-to-go solutions currently available for our selected GPS modules:

Assisted GPS ( AGPS)
Enable module to perform fast position during start-up using preloaded ephemeris and almanac data.

Gtop Binary Protocol
Efficiently transfer and process coordinate message in 8 bytes binary protocol format using 8-bit micro controller, without the need for parsing, conversion and huge C+ + string libraries.

10 Hz Update
True 10Hz update rate for high-speed applications.

One sentence
Simplifies standard NMEA sentence into a shorter Gtop proprietary protocol for a more efficient data processing. Also can pre-calculate data such as distances between two points within the GPS module to save calculation cycle on host micro controllers!

Power Periodic Mode
Achieve maximum power saving by automatically enters and exit sleeping mode, great for mobile and camera devices. Saves power consumption by ~ 80% !

Magnetic Variation
Finds true geographical north instead of the ever shifting magnetic north. Useful for marine and military applications!

Navigation Speed Threshold
Reduce position drift typically observed on GPS devices.

RTCM/ DGPS
Enhance position accuracy using data from ground-based reference stations.

Datum
Adjust the datum type to match map data. Total of 223 different datums are supported.
