THE PAGES DISAGREE and this was built: the bus of table (1) (T1 and T2), which table (2)'s face areas confirm and which gives the 2.2 m height and 1.7 m width that keeptrack.space (a catalogue site, read through a search extract and NOT OPENED; scene/models.js cites its satellite/43707 page) gives for this craft; the CAST solar area of 20.44 m2 of tables (1) and (2), NOT ESA's ~27 m2 and NOT that site's 'span of approximately 10 meters' (which does not fit 20.44 m2 on panels as wide as the body). NOT BUILT: SECM-A and SECM-B (2.55 to 2.80 m long, 10.8 m2). A second sanity check, not a source for the build: a Shanghai Observatory ILRS talk (ilrs.gsfc.nasa.gov/lw16/docs/presentations/tar_7_Wanzhen.pdf, read through a search extract, NOT OPENED) gives the COMPASS-M1 test craft's retroreflector array as 42 cubes of 33 mm on 31.6 x 28 cm. NOT CITED, READ OFF THE PICTURES AND ESTIMATED: how T2 sits on T1 (at one end, flush with its edge, on the Earth face), the round array's size (0.82 m) and its 28 cups, the retroreflector plate (0.38 m, 37 round cubes of 50 mm), the inter-satellite-link plate (0.36 m, 5 x 5 elements), the ring antenna, the boxes and corner units, the 1.19 m ring and its thirteen bolts on the far deck, the four-coloured square, the yokes (0.95 m) and hinge blocks, the panels' shape (three of 1.68 x 2.03 m a wing: the width from the drawing, the length from the cited area), the colours. NO PAGE OPENED GIVES THE PANELS' SIZE, so the wing's 15.5 m span is the area of the cited table spread on the drawing's panel width. ## References - [Dilssner et al.

PS4 has three variants L1.6, L2.0 and L2.5'; the same article: the third stage has 'a Kevlar-polyamide fibre case', and during the combined coast 'burnt-out PS3 remains attached to PS4' (which is why the gold Kevlar case and the nozzle hang under the stage in ISRO's photographs).

NOT SEEN IN ANY PICTURE and drawn only because the stage has them: the two L-2-5 engines under the tank, inside the skirt (their size is ours). THE PICTURES DISAGREE about the skirt: the 2008 photograph stands the stage on a brown ribbed drum (a handling fixture, not drawn); the 2019 and 2023 photographs hang it from a black ribbed cone under the ring (drawn). Whether that cone stays with the stage in orbit no opened page says.

That page does not say which axis is which: 15 m is read as the span over the wings, 6.1 m as the height of the core with its sensor head, and 6.7 m as the depth over the folded radiator doors.
