Description
Le récepteur AgGPS 372 avant-gardiste et de haute qualité de Trimble établit la norme pour les années à venir. Ce récepteur intelligent à 220 canaux suit en simultané pas moins de 44 satellites des systèmes GPS et GLONASS, et Galileo à l’avenir. De ce fait, ce récepteur convient à merveille aux applications exigeant une haute précision et pour lesquelles la réception des signaux laisse parfois à désirer, comme c’est le cas par exemple en lisière de forêt.
Le modèle AgGPS 372 peut recevoir tous les signaux de correction disponibles et, de ce fait, il peut être utilisé pour de nombreuses applications. Son robuste boîtier étanche à la poussière et à l’eau est identique à celui de ses prédécesseurs, à savoir les modèles 252 et 262. Les différents ports série et bus CAN permettent la transmission de données de positionnement (NMEA) et d’impulsions de vitesse. Grâce à la technologie xFill, ce récepteur peut rester 20 minutes sans signal de correction « RTK fixed ».

Features
– 220 GNSS tracking channels, which can track up to 44 satellites
– GLONASS tracking ability
– Submeter differential accuracy (RMS), assuming at least five satellites and a PDOP of less than four
– Combined GNSS/DGNSS receiver and antenna
– AgRemote utility with four-button keypad to configure and view system properties. You can download this utility from the Trimble website at www.trimble.com.
– LED status indicator
– The receiver outputs a 1 PPS (pulse per second) strobe signal on both ports. This
signal enables an external instrument to synchronize its internal time with a time
derived from the very accurate GNSS system time.
– Radar output
– WAAS and EGNOS differential correction compatibility
– EVEREST™ multipath rejection technology
– OmniSTAR HP, G2, XP, and VBS positioning compatibility
– Trimble CenterPoint RTX capability
– Two ports that support both CAN 2.0B and RS-232:
– CAN J1939 and NMEA 2000 messages
NMEA-0183 output: GGA, GLL, GRS, GST, GSA, GSV, MSS, RMC,
VTG, ZDA, XTE (the default NMEA messages are GGA, GSA, VTG, and
RMC)
Note – PTNLDG, PTNLEV, PTNLGGK, PTNLID, and PTNLSM are Trimble
proprietary NMEA output messages.
– RTCM SC-104 output
– Trimble Standard Interface Protocol (TSIP) input and output
