The web-based scheduling tools for astronomical observatories

Efficient observation planning is required in the demanding space environment. The WebPlan project's goal is to equip sensor owners, astronomers and SST operators with sophisticated scheduling tools that take into account sensor availability, visibility of objects and environmental statistics, and look for the best opportunity windows.
The Webplan suite integrates well into a single environment, from sensor management, through scheduling and data management, using the tools developed previously for astronomical observatories.

Sensor timebooking

Allocate time on a sensor, either for observations or maintenance

Automated scheduling

Ability to send an SCM-program to the sensor

CLI and APIs

Command-line tools and APIs available


Data access secured using OAuth2 standard

From scheduling to TDM

The Webplan suite sents the observation programs to the sensor and waits for the data to be received. Once observations are done, the sensor's processing pipeline can upload data to the AstroDrive. It can be either raw, FITS data or TDM, or both. The Webplan allows then to visualize the results in the browser, and monitor the progress of the campaign.
