Acquisition raster
A beam footprint walks a serpentine search raster across a sky box and flies back up the left edge, relighting the marked source cell each time it crosses it.

Groundstation
15 animationsArray combining
Four apertures of different diameters phase into the array one at a time and each one steps the combined gain column up a quarter of its scale.
CSSBeam sweep
A polar antenna pattern swings its main lobe and sidelobes across the sector and back, lighting the target bearing each time the boresight crosses it.
CSSBoresight pointing
A pointing-error marker spirals out from the centre of an azimuth/elevation crosshair and back onto boresight while the accuracy gauge beside it empties and refills.
CSSCarrier lock
A carrier spike drifts out of the receiver capture window and is pulled back into it, standing tall again against a noise floor that rises while the loop is unlocked.
CSSDeep space subnet
Three tracking complexes spaced around a turning longitude ring take the downlink in turn, each lighting as it comes to face the target ray.
CSSDoppler residual
A tracking marker rides the predicted Doppler curve down through closest approach and back while the frequency tick on the left-hand scale follows it.
CSSElevation mask
An elevation cursor climbs a pass curve from the dashed mask line toward culmination and back while the visibility window bar beneath closes to the chord it cuts.
CSSFrame sync
A telemetry tape slides past a fixed sync window and the frame brackets latch shut each time the attached sync marker registers inside it.
CSSLink budget
A waterfall of gain and loss stages steps down from transmit power to the receiver threshold while the link-margin caliper at the foot re-measures itself.
CSSRecorder playback
The segmented onboard recorder empties one cell at a time past the read head while the freed packets leave down the rail to the receiver.
CSSRound-trip light time
A command packet runs the range rail out to the spacecraft and the echo returns, with the delay readout beneath filling on the outbound leg and draining on the return.
CSSStation handover
The active tracking segment travels three overlapping station visibility windows on one timeline, stepping down into the next window inside each overlap.
CSSSystem noise temperature
The sky noise contribution grows and pushes the fixed receiver term along a stacked temperature bar, carrying the total tick toward the dashed spec limit and back.
CSSViterbi survivor
The surviving path traces forward stage by stage through a convolutional decoder trellis, holding once decoded while the discarded branches breathe behind it.
