Lassen-SK8 Embedded GPS Module 1-1
1 Starter Kit
The Lassen-SK8, based on Sierra
TM
GPS technology, delivers an unmatched level of
performance for embedded GPS applications. Sierra technology is Trimble's 8-channel
GPS architecture based on two ASICs, the Scott RF ASIC and the Scorpion DSP.
The Scott RF ASIC features:
• Double down-conversion process
• Higher sensitivity
• Lowest power consumption
The double down-conversion process improves immunity to in-band jammers. The system
provides a higher sensitivity which allows Lassen-SK8 to track weak satellites and
improves position availability in environments with obscured coverage.
The Scorpion ASIC provides the following features in a single package:
• Integrates an 8-channel DSP with 4 correlators per channel
• 32-bit microprocessor
• Real-time clock
• DUART
The 8-channel, 32-correlator design provides extremely fast cold starts while delivering 2
meter DGPS performance. The high level of integration provides a small footprint (3.25"
x 1.25" x 0.40") and contributes to the lowest power consumption (.75 watts) for a
complete GPS receiver. The combination of small size and low power consumption allows
Lassen-SK8 to be embedded in small battery operated devices and in devices where heat
dissipation must be minimized.
The Starter Kit makes it simple to evaluate the Lassen-SK8 module's exceptional
performance. The kit includes the following:
• Lassen-SK8 receiver installed inside an interface unit
• Magnetic mount antenna
• AC power adapter
• Serial interface cable
• GPS Tool Kit Software used to communicate with the GPS module
