Satellite tasking

Satellite tasking is the process of commanding an Earth-observation satellite to collect a new image of a specific area of interest at a specific time, as opposed to buying an existing archive image.

Tasking vs archive

Earth-observation imagery comes in two forms: archive (already-collected scenes you buy off the shelf) and tasking (a fresh collection you request for a future pass). Tasking matters when you need a current image, a specific look angle, or coverage of an area that hasn't been imaged recently.

A tasking request specifies the area of interest (AOI), the time window, and constraints such as maximum cloud cover, maximum off-nadir angle, and required resolution. The operator's planning system then checks whether any satellite can satisfy those constraints during the window.

Why feasibility planning is the hard part

Before placing a tasking order you need a feasibility answer: which satellites can reach the AOI in the window, at a usable look angle, and how often. This depends on each satellite's orbit, swath, agility, and the AOI's latitude — and across many satellites it becomes a multi-constellation planning problem.

PassPrediction computes this feasibility neutrally across operators: it predicts the passes, the achievable off-nadir angles, the revisit cadence, and the cloud outlook, so you can compare options before committing to any single provider.

Frequently asked questions

What is the difference between tasking and archive imagery?

Archive imagery is already collected and sold off the shelf; tasking requests a new collection of your area at a future satellite pass, letting you control timing, look angle, and freshness.

How far in advance do you task a satellite?

It depends on the operator and priority tier, from same-day urgent tasking to multi-day standard tasking. Feasibility depends on when the satellite next passes over your area at an acceptable angle.
