Javad DELTA, DELTA D and DELTA Q

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

For the first time in the GNSS history we offer up to 100 Hz RTK. 216 channels of single or dual frequency GPS, Galileo and GLONASS in a small attractive, sturdy, and watertight box. DELTA contains either TRE-G2T, TRE-G3T, or TRE-G3TAJ, DELTAD contains Duo-G2 or Duo-G2D, and DELTAQ 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 DELTA receivers work with optimum signal available creating the most reliable results, saving your time and money.

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

The on-board power supply on DELTA receiver accepts any voltage from +10 to +30 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. DELTA receiver also includes TriPad (two LEDs, ON/OFF and function button). In addition, the receiver comes with large amount of flash for data storage. The CAN interface in DELTA receiver is provided complete with all associated hardware and firmware, not just the CAN bus. The same is true with all the serial RS232/RS422 ports in our receiver. Simply stated, additional functions are not needed to incorporate any of our DELTA Receiver in most applications.

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

DELTA.
Universal standard GNSS receiver The well-designed and implemented DELTA receiver will be very useful in your surveing applications, and work can begin within minutes of arriving at a site. Multy-porpose DELTA receiver - joint venture for geophisical studies, dam operations, surveying,mapping,monitoring, etc.

DELTAD.
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. DELTAD combines both boards connected internally in one unit.

DELTAQ.
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. DELTAQ can also operate in the RTK or DGPS modes receiving differential corrections from an external base station to provide differentially corrected position and velocity.
