elcano Key Features
The two basic concepts in elcano are Analysis and Configurations. Configurations consist on the definition of the basic blocks that will be used for analysis definition. For instance, the constellation to be optimized is not configured within the corresponding analysis but picked up from the available constellations list, which is defined and managed in the corresponding configurations module.
Although this is completely transparent to the user, elcano implements an internal database to manage all items needed for the proper execution of the tool, namely analysis and configuration items.
elcano is launched as any standard Windows application. The main MMI window is shown the figure below:
As can be seen, the main window allows both running analysis and configuring of the different elements that will be part of the scenarios.
From the Analysis panel, it is possible to perform the following tasks:
- Optimize a constellation for user-defined target performances
- Determine the failure satellite statistics of a given constellation
- Analyze constellation stability over time
- Compute user positioning accuracy figures over a given service area
- Compute positioning availability and continuity risk over a given service area
- Characterize the covariance of the Orbit Determination and Time Synchronization (ODTS) process
- Characterize the covariance of a Precise Point Positioning (PPP) method
Graphical visualization capabilities are provided within each module. Clicking on the Configuration tab (wrench icon) will display the Configuration panel, as shown in figure below:
From this panel, it is possible to perform the following tasks:
- Constellations configuration, including constellation templates and satellite failure models
- User Equivalent Range Error (UERE) budgets
- User service areas
- Reference stations network
