GPS-27 |
|
|
| |
 The
Rikaline GPS-27 GPS Engine Board
is designed based on SiRF Star III new generation
architecture with low power consumption, small size (16 x 20mm) and
easy integrated for a broad spectrum of OEM system applications. It
acquires satellite 20 channel parallel and tracking 12 at a time.
The 200,000 effective correlators ensure fast TTFF and fast TTFF at
low signal level. |
| |
| The GPS-27 meets strict needs such as car navigation,
mapping, surveying, security, agriculture and so on. Only clear view
of sky and certain power supply are necessary to the unit. It communicates
with other electronic utilities via compatible TTL and saves critical
satellite data by built¡Vin backup memory. The Trickle-Power allows
the unit operates a fraction of the time and Push-to-Fix permits user
to have a quick position fix even though the receiver usually stays
off. |
| |
| To minimize the space and cost, we provide you GPS-27
without patch antenna and some components which you may have in your
main board. |
