Add a payload
Adds a payload under a parent spacecraft resolved strictly by id. The server assigns the lowest-free slot index [0,7]; the 9th sensor is refused with 422 PAYLOAD_LIMIT_EXCEEDED. Returns 404 if the parent spacecraft does not exist.

Path Parameters
Parent spacecraft id
Body
application/json
One payload (sensor): boresight axis + four-shape field of view (DKR-1 §3.3).
Body-frame boresight axis. One of X+, X-, Y+, Y-, Z+, Z-.
Available options:
X+, X-, Y+, Y-, Z+, Z- Example:
"Z+"
Field-of-view shape primitive (CONICAL, RECTANGULAR, ELLIPTICAL, POLYGON). Determines which conditional shape parameters are required.
Available options:
CONICAL, RECTANGULAR, ELLIPTICAL, POLYGON Example:
"CONICAL"
Operator-supplied payload name.
Maximum string length:
100Example:
"EO Camera"
Payload mounting position X in metres (body frame; may be negative).
Example:
0.1
Payload mounting position Y in metres (body frame; may be negative).
Example:
0
Payload mounting position Z in metres (body frame; may be negative).
Example:
-0.2
Optical focal length in millimetres (mm). Optional optical characteristic for downstream modelled-GSD; when present must be positive and finite. Independent of the FOV group — partial optics is tolerated.
Example:
120
Cone half-angle in degrees (CONICAL only). Range (0°, 90°]; 90° accepted.
Required range:
0 < x < 90Example:
30
FOV half-height in degrees (RECTANGULAR / ELLIPTICAL only). Range (0°, 90°) strict.
Required range:
0 < x < 90Example:
20
FOV half-width in degrees (RECTANGULAR / ELLIPTICAL only). Range (0°, 90°) strict.
Required range:
0 < x < 90Example:
10
Payload off-nadir along-track slew limit in degrees — how far off-nadir the payload may be pointed along the velocity vector. Optional; range (0°, 90°]. Independent of the FOV group and of the optics fields.
Required range:
0 < x < 90Example:
18
Payload off-nadir cross-track slew limit in degrees — how far off-nadir the payload may be pointed across the velocity vector. Optional; range (0°, 90°]. Independent of the FOV group and of the optics fields.
Required range:
0 < x < 90Example:
30
Detector pixel pitch in micrometres (µm). Optional optical characteristic for downstream modelled-GSD; when present must be positive and finite. Independent of the FOV group — partial optics is tolerated.
Example:
5.5
Polygon circumscribed (to-vertices) angular radius in degrees (POLYGON only). Range (0°, 90°) strict. Datum = OUTSIDE_CONE_TOUCHING_POLYGON_AT_VERTICES (DA-3).
Required range:
0 < x < 90Example:
30
Number of polygon sides (POLYGON only). 3 ≤ N ≤ 1000.
Required range:
3 <= x <= 1000Example:
6
