Telemetry controls permit to configure data to be stored or transmitted on the system. There are 4 main items that can be configured within this panel:

TypeDescription
Data LinkConfigures the variables to send throughout the data link channel.
Onboard LogSets the variables to be stored on system Log. (on Veronte SD Card)
User LogUser Log for custom applications.
Fast LogSaves data at the maximum frequency available on the system. Recording time depends on the selected variables.

Telemetry – Items

Configuration display permits to enable the desired variables for each telemetry file and to set the maximum and minimum values together with precision for each one.

Data Link

The Data Link contains the variables sent between Veronte Units and Veronte Pipe. By default, the system provides one Data Link that represents the connection between the air autopilot and the software (Pipe). Veronte Air sends the variables to Veronte Ground, being processed when they arrive there by Veronte Pipe. This Link is the one that provides the variables observed and configured in the system using the “Workspace” menu.

Telemetry Configuration Menu

Pipe permits the creation of more Data Links too. The user has to configure which unit sends the information and which receives it, the unit that processes the data (Microcontroller of the autopilot or Veronte Pipe) and the sending rate. As an example, another possible data link could be set between the Air and Ground autopilots directly (without Pipe) and used to send the position of the UAV to the Ground autopilot for the configuration of a tracker. This Data Link example is presented in the following figure.

 

Data Link (Ground/Air)

The autopilot “Mentor” will send the Latitude, Longitude and AGL to the autopilot with address 255 (Ground) for internal processing (MCU 0). The sending rate is set to 10 Hz.

Caution!! If the number of variables enabled for telemetry communication are higher than the maximum supported by the system, the latest variables will not be sent, so they will display a zero value if shown in the workspace.

 

Onboard Log

The Onboard Log determines the variables that are being stored on the autopilot SD Card. In this case, there are not sending/receiving units so the only thing to configure here is the list of variables that will be saved on the autopilot internal memory for a further download and processing. The SD management task is “Low”, which is an execution level running at 30 Hz.

Onboard Log

User Log

The user log contains the variables that are stored according to an automation created by the user. Considering an example, in a photogrammetry mission it is important to record the aircraft location when the photo is taken, so a user log could be used to record a certain set of variables (position, speed, direction…) each time a photo is taken.

User Log

In order to create a “User Log” action where an entry is added to the log when a certain set of events are accomplished check section 6.6  of the manual (Actions).

 

Fast Log

The fast log store the specified variables at the maximum rate available on the system. This tool could be used to save information in an operation that happens extremely fast such as missile launching. The time that this logging process lasts depends on the number of variables being saved.

When a variable is enabled in the Fast Log, a new button will appear in the Veronte Panel. The user must click on it when he wants to activate the fast log tool.

The downloading of the information of an operation depends on how it has been stored, i.e depends on the type of log (data link, onboard, user or fast). Visit section  10 of the manual to see the information related to the postflight tools contained in Veronte Pipe.
