6.8 SatService-ACU-Prediction

This page describes the SatService-ACU-Prediction device. This device is a supplement to the SatService-ACU-ODM device driver for the sat-nms ACU outdoor module.

The SatService-ACU-Prediction device adds access to the ACU's feature to calculate a 100 datapoint table from a given I11 or TLE dataset stored in the ACU's memory. This requires an ACU2 outdoor module (software version 3.0 or higher). The SatService-ACU-Prediction device works like a separate device driver which talks to the ACU-ODM in parallel to the basic SatService-ACU-ODM driver. The SatService-ACU-Prediction device may be configured in the same or in a different device thread (aka. INTERFACE), the HTTP protocol used does not demand any restriction on this.

To use the SatService-ACU-Prediction device, select the Type of ephemerides to use, the memory number, start time and time increment. Finally click "SUBMIT" and the result will be shown.

Using the device in an automated or remote controlled environment works exactly in the same way: Set the variables 'ephemerisMode', 'memoryNumber', 'startTime' and 'timeIncrement' to specify the parameters of the request. Finally set the 'predict' variable to an arbitrary value to send the request to the ACU-ODM

The 100 data points then can be read from the 'result.nn' variables, where 'nn' is in the range of '00' to '99'. The variable 'state' holds information about success or failure of the operation. If the request failed, all 'result.nn' variables contain empty strings and the 'state' variable tells about the failure's reason. Please give the device about one second time to answer after sending the request and before you read the result strings.

Device window pages

The following table shows which device window pages are available with this individual device type. Tool-bar functions not mentioned here are described at the general description of device windows .

• --- The main parameter page displays/controls request parameters and the result.
• --- The device info page.
• --- The maintenance page. The configuration parameters described below are set at this page.

Configuration parameters

At the maintenance page of the device window there is one configuration parameter which must be set to make the software talk to the antenna controller.
