Performance
The NavCom SF-2040 receivers use the NavCom
NCT-2100D GPS Engine including the fourth
generation Touchstone™ ASIC family, of which more
than 40,000 are in use worldwide. Incorporated are
NavCom patented interference suppression and
multi-path mitigation, a 5Hz raw data rate (up to 50Hz
optional), and 5Hz geodetic-quality positioning (up to
25Hz optional).
„ RTK
Extend™
1
RTK Extend™ enables continuous RTK-level
positioning accuracy during radio communication
outages by utilizing NavCom’s global StarFire™
corrections.
Traditionally, when an RTK rover loses
communication with the base station, it is unable to
continue to provide position updates for more than a
few seconds, resulting in user down-time and
reduced productivity. With RTK Extend™, a NavCom
StarFire™ receiver operating in RTK mode, can
transition to RTK Extend™ mode and maintain
centimeter level positioning during communication
loss for up to 15 minutes. RTK Extend™ allows more
efficient and uninterrupted work, enabling focused
concentration on the work rather than the tools.
„ A complete portable system
The LAND-PAK is a highly integrated solution
designed for productivity with minimal setup time and
maximum portability. Covering the entire land survey
process, it contains a complete base and rover
system for field data collection. Optional software for
data analysis and processing is also available.
