HiPerII Chapter 1 

 
The HiPerII receiver is a multi-frequency, GPS+ receiver built to be the most advanced and 
compact receiver for the surveying market.  The receiver is a multi-function, multi-purpose 
receiver intended for precision markets. 
Precision markets means markets for equipment, subsystems, components and software for 
surveying, construction, commercial mapping, civil engineering, precision agriculture and 
land-based construction and agriculture machine control, photogrammetry mapping, 
hydrographic and any use reasonably related to the foregoing. 
The HiPerII can receive and processes multiple signal types ( including the latest GPS L1, L2, 
C/A, L2C  GLONASS L1, L2, C/A signals ) improving the accuracy and reliability of the survey 
points and positions, especially under difficult jobsite conditions.  The multifrequency and 
GPS+ features of the receiver combine to provide a positioning system accurate for any survey.   
Several other features, including multipath mitigation, provide under-canopy and low signal 
strength reception.  The receiver provides the functionality, accuracy, availability, and integrity 
needed for fast and easy data collection. 
 
 
 
 
 
 
 
 
 
 
 

 

 
Surveying with the right GPS receiver can provide users accurate and precise positioning, a 
requirement for any surveying project.  This section gives an overview of existing and 
proposed Global Navigation Satellite Systems ( GNSS ) and receiver functions so that basic 
operating principles can be applied.
