JAVAD GNSS Distributor in India - Janak Positioning and Surveying System Pvt. Ltd.


ALPHA 2 receiver is based on our TRIUMPH2/TRIUMPH Technology implemented in our TRIUMPH Chip. For the first time in the GNSS history we offer up to 100 Hz RTK.

864 channels of dual frequency GPS, Galileo, GLONASS, BeiDou, QZSS and IRNSS in a small attractive, sturdy, and watertight box, which contains TR-3N board.

216 channels of single or dual frequency GPS, Gallileo and GLONASS in a small attractive, sturdy, and watertight box, which contains either TR-G2, TR-G3, TR-G2T or TR-G3T board.

The on-board power supply on ALPHA 2 receiver accepts any voltage from +5.5 to +40 volts and delivers clean filtered voltage where needed. This eliminates the risk of power contamination (ripples) that can be created when clean power is generated elsewhere and delivered to the board via cables. ALPHA 2 receiver also includes TriPad (two LEDs, ON/OFF and function button) exclude TR-G2 version, Bluetooth wireless technology. In addition, the receiver comes with large amount of flash for data storage. Simply stated, additional functions are not needed to incorporate any of our ALPHA 2 in most applications.

In addition to timing strobe and event marker, the ALPHA 2 receiver includes the option of complete IRIG timing system.
