Overview
Topcon Positioning System’s HiPer Lite and HiPer Lite+ receivers
are dual-frequency, GPS+ receivers built to be the most advanced
and compact receiver for the surveying market. The HiPer Lite and
HiPer Lite+ are multi-function, multi-purpose receivers 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 HiPer Lite and HiPer Lite+ can receive and process both L1
and L2 signals, improving the accuracy of your survey points and
positions. The dual-frequency and GPS+ features of HiPer Lite and
HiPer Lite+ combine to provide the only real time kinematic (RTK)
system accurate for short and long baselines. Several other features,
including multipath mitigation and co-op tracking, provide under-
canopy and low signal strength reception. The receivers provide the
functionality, accuracy, availability, and integrity needed for fast
and easy data collection.
Principles of Operation
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 GPS and receiver functions to
help you understand and apply GPS principles, allowing you to get
the most out of your receiver.
GPS Overview
The Global Positioning System (GPS) is a satellite-based, line-
of-sight radio navigation system run by the United States
Department of Defense (DoD). This system offers a global, all
weather, 24-hour positioning, velocity, and time service to any
