Receiver boards

DataGrid receiver philosophy is unique. You may use a single receiver in your application or you may combine as many as you want. With the appropriate firmware these will combine to give you as much receiver resources your application may call for. Each receiver therefore produces raw data measurements (along with standalone navigation and housekeeping data). The raw data are then combined in a single processing unit. Boards can be supplied to produce raw data or as a combination with a board that has a processor engine for RTK.

Key Benefits

  • Each receiver board has its own radio frontend with separate frequency paths for each sub-band that the digital portion is made to receive. For example GPS L1, GPS L2, GPS L5, GLONASS L1, and GLONASS L2 each have their separate and dedicated frequency path for optimum performance. This is the "no-compromise" approach to performance. Compare to receiver designs that simply widened theirs thereby increasing their unwanted background, sacrificing quality for quantity of trackable satellites.
  • The digital receiver portion is reprogrammable. Its functions can therefore be optimized as transmissions may change or new codes may be transmitted. It is also possible to reallocate receiver resources to increase sensitivity or change the number of satellites that may be tracked. You may purchase OEM receivers with standard features and as your customer's needs evolve DataGrid can develop custom firmware/hardware features or you may want to differentiate your products to give them your brand specific "feel". For example, we could develop custom firmware/hardware that turns your high precision receiver into a highly sensitive one suitable for indoors use. This is an illustrative example only since we do not recommend using the highly distorted satellite signals found in the indoors environment for precision measurements.
  • Unlimited expandability through the ability to combine as many receiver boards as your application may require ....
  • High efficiency. Just turn on and off power to receiver boards as your need for resources change.

 

Antennae

DataGrid's precision survey antennae are factory configurable for multiple frequencies in the L-band, such as dual frequency GPS L1 and L2, or GPS/GNONASS L1/L2.  A stable phase center is achieved with a cavity backed, exponential planar spiral antenna element. Low weight is a key property for ease of use in the field and also for durability.

Key Benefits

  • Individually calibrated versions available for the most demanding precision applications.
  • Very light at 270 g they are the market leaders.
