; BeiDou B2a (5D) file-input example: 8-bit signed real IF.
; Tracks B2a_I (data) at 1 ms primary-code epochs; telemetry combines five
; epochs per symbol and applies 64-ary LDPC(96,48) decoding and CRC-24Q.
; GEO / BDS-2 (PRN 1-18 and 59-63) are not assigned B2a channels.
; GEO PRNs 1-5 and 59-63 are excluded: GEO B2a decoding/PVT is not supported.
; The 2026 reassignment places BDS-3 IGSO/MEO satellites at PRNs 6-8 and 11-14.
;
; PVT policy (B2a-only SPP):
; - RTKLIB slot 0 holds 5D; satwavelen BDS frq2 stays B3, lam[0] is c/FREQ5.
