JAVAD SIGMA

SIGMA receivers’ family is based on Javad's TRIUMPH Technology implemented in their TRIUMPH Chip and is designed to meet all the needs of today’s high precision GNSS satellite receiver market.

It offers up to 100 Hz RTK. 216 channels of single or dual frequency GPS, Galileo and GLONASS in a small attractive, sturdy, and watertight box. SIGMA contains either TRE-G2T, TRE-G3T, or TRE-G3TAJ, SIGMAD contains Duo-G2 or Duo-G2D, and SIGMAQ contains Quattro-G3D board.

With the ability to process GPS, Galileo and GLONASS L1/L2, E1 signals as well as SBAS and L5, E5 if necessary, the SIGMA receivers work with optimum signal available creating the most reliable results, saving your time and money.

SIGMAD and SIGMAQ receivers process the dual frequency code and carrier data from two, or four antennas to determine the three orientation angles and three dimensional position up to 100 times per second.

SIGMA is very useful in the most of high accuracy applications, such as reference stations and CORS.

The on-board power supply on SIGMA receiver accepts any voltage from +10 to +30 volts and delivers clean filtered voltage where needed. SIGMA receiver also includes TriPad (two LEDs, ON/OFF and function button), GSM module, UHF modem, and batteries. In addition, the receiver comes with large amount of flash for data storage. The CAN interface in the SIGMA receivers is provided complete with all associated hardware and firmware, not just the CAN bus. CANopen slave protocol is provided optionally. The same is true with all the serial RS232/RS422 ports in SIGMA.

SIGMA.

Universal standard GNSS receiver

SIGMA receiver includes TriPad (two LEDs, ON/OFF and function button), GSM/CDMA200 module, UHF modem, Bluetooth and Ethernet capability, up to two serial ports, up to two even markers and 1PPS timing strobes, and recargeable batteries.

The well-designed and implemented SIGMA receiver will be very useful in your surveing applications, and work can begin within minutes of arriving at a site.


SIGMAD.

Real-Time Heading

Usually, one needs two receivers interconnected through the serial ports. One of them is a moving base and another is a rover. SIGMAD combines both boards connected internally in one unit. SIGMAD is a powerful receiver for high accuracy applications, such as reference stations and CORS.


SIGMAQ.

Real-Time Attitude and Position calculation

The dual frequency code and carrier frequency data are
processed to determine the three orientation angles and
three-dimensional position up to 20 times per second.
SIGMAQ can also operate in the RTK or DGPS modes
receiving differential corrections from an external base station
to provide differentially corrected position and velocity.
