RT17 Service

RT17 is a streaming service used to encode and transmit real time GPS measurements. RT stands for Real Time, and 17 refers to the record type 17 GPS measurement information stored in Trimble DAT and T00 files. This is the basic information used to produce GPS positions and corrections. RT17 was designed to allow similar information to be streamed for real time applications. The format has been expanded beyond basic measurements and now includes:

Stream Control

The epoch interval is used to specify that rate at which the measurements and/or positions are sent out the port. The output rate varies from 0.1 second to 10 minutes. The rate selected is based on the application. High data rates are used for highly dynamic applications, whereas low data rates are used for long-term monitoring applications. If the receiver has mixed use, multiple RT17 ports can be configured with different data rates, and applications can connect to the appropriate port.

Two checkboxes are provided to control the information that is included in the stream.

Stream Options

There are various options that modify the information included in the RT17 stream. Each is controlled by a checkbox on the web-browser interface. The options are:
