Receiver
This chapter discusses the receiver architecture, mechanical layout,
and application notes related to a successful integration of the SBX-3
receiver.
3.1 LED Indicators
The SBX-3 engine has two surface-mounted red LED indicators
located on the opposite side of the board in relation to the header
connectors. One LED is for signaling the power-on status of the
receiver, labeled with ‘PWR’ silk-screening and the other is for
indication of signal acquisition, labeled with ‘LOCK’ silk-screening.
When power is applied to the SBX-3, the power LED illuminates and
when the SBX-3 achieves signal acquisition on a valid DGPS beacon,
the lock LED illuminates.
The following figure shows the SBX-3, front and back, including the
illumination of the power and lock LED indicators.
