1 Introduction
RoyalTek RSA-1500L low power and small form factor board is the newest generation
of RoyalTek smart antenna GPS module. The smart antenna GPS module is powered
by SiRF Star III technology and RoyalTek proprietary navigation algorithm that
providing you more stable navigation data. Parallel design is the major new feature of
RSA-1500L.
The smallest form factor and parallel design is the best choice to be embedded in a
portable device and receiver like PND, mobile phone, car holder, personal locator,
digital camera and vehicle locator. The excellent sensitivity of RSA-1500L gets the
great performance when going though the urban canyon and foliage
Product Features
20 parallel channels
Extreme fast TTFF at low signal level
Operable from 3.3V/48mA continuous mode.
Wire to board connector
TCXO design
