Mandala variables

All parameters of the vehicle state are organized in structured tree of values. The definition of the structure, called mandala is described in this section.

Data items are shared between node modules and other nodes by means of publisher/subscriber framework, which is managed by mdb broker.

The tree consists of the following levels:

  1. class: sns, ctr, est, cmd (2 bits);
  2. type: nav, env (1 bit);
  3. subsystem: up to 15 subsystems (4 bits);
  4. field: up to 15 fields (4 bits);

The unique identifier of any value consists of 11 bits. Each packet in the network uses mandala uid to address pub/sub values.

Data access

Mandala tree is available in GCS Java Script context and facts tree and created for every recognized vehicle.

GCS UI and JS context have simplified structure, where type component is omitted. Moreover, on GCS side radians are converted to degrees.

F.ex., in GCS Terminal, which evaluates in JS context, any mandala value item can be accessed as class.subsystem.field.

  • cmd.pos.altitude=800 will set commanded altitude to 800m;
  • ctr.wing.flaps=0.8 extracts flaps to 80%;
  • cmd.proc.mode = proc_mode_TAXI will enter TAXI procedure;
  • cmd.proc.action = proc_action_next will trigger the next stage of the current procedure;

Data synchronization

Since GCS has dedicated mandala tree for every detected vehicle, the data in this tree (values) is synchronized with the current vehicle state by means of:

  • telemetry stream (usually this is the only data source);
  • any data packets received and decoded from interfaces;

On the onboard network and between nodes the data is synchronized by mdb module.

Some special mandala fields are synchronized by bundles. This happens when to have atomic data packages is required. F.ex., for IMU sensors data packages or to set commanded position vector (lat,lon).

The fields beyond cmd.env group do not have any value associated with them, but are used as UIDs of data packets to implement different protocols for data transfer.
