Data Sampling
GPS L1 and L2 raw data is 1 to 5Hz in the standard
configuration and as an optional upgrade as fast as 10,
25, and 50Hz via either of the two serial ports. The
PVT
(Position, Time, & Velocity) data is also 1 to 5Hz in the
standard configuration and as an optional upgrade as
fast as 10 and 25Hz for high dynamic applications.
„ GPS Performance
The NCT-2100 GPS engine at the heart of the SF-2040
incorporates several patented innovations. The receiver
provides more than 50% signal to noise ratio advantage
over competing technologies. The benefit to the user is
improved real time positioning, with independent tests
proving the NCT-2100 to be the best receiver when
facing various
multipath environments.

Rugged Design
The rugged design of the SF-2040 system components
provides protection against the harsh environments
common to areas such as construction sites and can
withstand a 2-meter drop onto a flat hard surface.
Units have been tested to conform to MIL-STD-810F for
low pressure, solar radiation, rain, humidity, salt fog,
sand, and dust.
