HAICOM HI-203E

12 kanalovy GPS prijimac (L1, C/A Code), bez konektoru pro externi antenu. Je to jen gps modul, tedy zadny displej, klavesnice, atd (pro funkci potrebuje sw na PC anebo PDA). General GPS function in Standard NMEA 0183 V 2.2 output protocol,supported commands are: GGA, GLL, VTG, RMC, GSA, GSV. GPS postavena na chipu EverMore BBP1202. Pouzdro neni vodotesne!
Mini-DIN PS/II to PDA plug (moznost pripojit ruzne koncovky, DB9, USB, PDA, atd)
Mini-DIN/USB prevodnik je postaven na chipu PL-2303 (pl2303 modul pro linux)

lze pripojit prevodniky pro ruzna PDA; pro pripojeni k PC jsem pouzil USB prevodnik. V prijimaci je magnet, lze snadno pripevnit na kovovy podklad. Obsahuje litiovou baterii pro zalohu dat, pokud modul neni pripojen k PC; to umozni zrychleny start po pripojeni. Dale obsahuje LED diodu, ktera vizualne zobrazuje stav (blika, pak nema dostatek satelitu pro urceni polohy; trvaly svit, pak platna poloha)
Na konektoru Mini-DIN je signal, ktery lze pouzit pro presnou synchronizaci casu; je aktivni po dobu 1us na zacatku kazde sekundy; pokud je prijimac synchronizovan.

Nejakym zpusobem lze zapnout i GLL vety, pripadne i EverMore binarni protocol.

Jako GPS software pro Linux treba gpsdrive a gpsd server.
Pro test zakladni funkce ve Windows: http://www.commlinx.com.au/gps_diag.htm (sorry, ale nevim ze by existovalo neco podobneho pro Linux...)
