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:



Data Link

Configures the variables to send throughout the data link channel.

Onboard Log

Sets the variables to be stored on system Log. (on Veronte SD Card)

User Log

User Log for custom applications.

Fast Log

Saves data at the maximum frequency available on the system. Recording time depends on the selected variables.

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.

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, as well as the writing frequency (30 Hz in the example of the image below).

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 Automations.

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.

Compressing options

Veronte includes some compression tools that may be useful for increasing the amount of information transmitted in a certain bandwith or stored in a log. Each variable can be compressed separately in each log.

There are different types of compression available:

Veronte Configuration - Compression options

Compression options

  • Uncompressed: the variable is taken in its full length, with no value modification.

  • Compress (Bits signed): specify the number of bits to be compressed to (negative values accepted). It is necessary that the user configures Encode/Decode options.

  • Compress (Bits unsigned): specify the number of bits to be compressed to (no negative values accepted). It is necessary that the user configures Encode/Decode options.

  • Compress (Decimals): the variable is compressed according to the number of decimals specified and the range specified (max and min values). The resultant compression (number of bits) follows the relation \((max-min) \cdot 10^{decimals}\) - which yields the encoding of the maximum value of the range (and the number of bits necessary for that). The range needs to be specified on the Encode - Min/Max field.

  • Encode/Decode: these values are used to apply a scaling factor after the transformation from binary to decimal value, or before the transformation from decimal to binary value.

In the example shown below, the Heading variable with 3 decimals will be compressed, so instead of using 32 bits, it will only require 19 bits.
