All systems come with a build-in GPS receiver. With a system intended for vehicle use,
we believe this must be a standard feature.
Specifications:
· Open sky cold start 29 seconds,
· Signal detection better than -161dBm,
· Reaquisition sensitivity -155dBm,
· Position accuracy 2.5m CEP,
· Multipath detection and suppression,
· 51 channel acquisition,
· 14 channel tracking,
· SAW filter for 30dB out of band suppression,
· Update rate 1-10Hz,
· Operating limits 18000m or 515m/s,
· Fakra antenna socket.
Instant on:
When the system is switched off, the system controller will activate the GPS receiver
every 5 minutes. This way, the GPS receiver can maintain hot-start aquisition performance.
In addition, the position updates can be used for logging or geofencing.
Geofencing:
During power down state, the system controller can monitor the periodic updates and wake the
system if the geofence is passed. This is not intended to replace a regular GPS based alarm
system, but it can serve as a backup.
