14 SUPERSTAR II User Manual Rev 3
Chapter 1 Introduction
The SUPERSTAR II, see Figure 1 below, is a quality GPS receiver for embedded applications. The
SUPERSTAR II has robust signal tracking capability even under difficult signal conditions.
The SUPERSTAR II is a complete GPS OEM sensor that provides 3D navigation on a single compact board
with full differential capability. The SUPERSTAR II is a 12-channel GPS receiver that tracks all in-view
satellites. It is fully autonomous such that once power is applied, the SUPERSTAR II automatically searches,
acquires and tracks GPS satellites. SUPERSTAR II receivers also have Satellite Based Augmentation System
(SBAS) capability, for example WAAS and EGNOS. When a sufficient number of satellites are tracked with
valid measurements, the SUPERSTAR II produces a 3-D position and velocity output with an associated figure
of merit (FOM).
