Telemetrie-Systeme

Die drahtlose Kommunikation zwischen VBOX-Produkten stellt oft eine wichtige Anforderung unserer Kunden an ein Testsystem dar. Dies kann z.B. eine Bluetooth-Verbindung zu einem Tablet-PC für die Datenausgabe in Echtzeit sein; die Übertragung von DGPS-Korrektursignalen, um eine hohe Positionsgenauigkeit der VBOX sicherzustellen; oder der Austausch von GPS-Messungen zwischen VBOX-Datenloggern in einem Open-Road-ADAS-Testaufbau.

Um das beste Telemetrie-System für Ihre Applikation zu ermitteln, ist oft eine Konsultation mit Ihrem VBOX-Händler notwendig. Je nach benötigter Reichweite, Bandbreite oder gesetzlicher Übertragungsbeschränkungen, kann das passende Telemetrie-System für Sie ermittelt werden.

VBOX NTRIP Modem

Veröffentlicht in Telemetrie-Systeme

NTRIP Modem RLACS250The VBOX NTRIP Modem allows a VBOX 3i RTK to receive positional correction data via Network RTK, without having to use a VBOX Base Station.

Correction messages received via the RTK network can be an advantage if testing is conducted tens of kilometres away from the base station, over large changes in elevation or where topographical obstacles could get in the way.

If RTK coverage is available, the VBOX NTRIP Modem allows for vehicle testing that requires high positional accuracy – such as when validating critical safety systems like AEB/ACC - to be conducted where a VBOX Base Station cannot be deployed.

What is Network RTK?

Network RTK utilises one or more Continuous Operating Reference Stations (CORS) to provide RTK data to a GNSS Rover, usually via mobile internet.

The most common method of Network RTK involves a two-way communication link which allows the roving vehicle to send its position to a service provider that is monitoring satellite observations from several reference stations around a country.

What is NTRIP?

Most network RTK systems are internet based and utilise a protocol called NTRIP (Networked Transport of RTCM via Internet Protocol). A constant internet connection is required to receive corrections, which can be done via a cellular modem, such as VBOX NTRIP, or a smart phone.

How does it work?

The VBOX NTRIP Modem enables the roving VBOX unit to send its position to the stations within the network – just as it would to a single VBOX Base Station. The NTRIP service provider will then calculate the appropriate corrections for the VBOX’s location based on the data from nearby reference stations. This correction information is then returned to the VBOX in the same RTCM format as is used for a single fixed base station.

In order to use this type of correction you have to register and subscribe to a cellular data plan with your local NTRIP provider, such as Topnet in the UK and Germany, Swepos in Sweden or Unavco in the USA.
