Parser and lookup helpers for ANTEX 1.4 receiver and satellite antenna blocks.
The ANTEX parser, satellite validity lookup, and PCO/PCV interpolation live in the Rust GNSS core. This module preserves Sidereon' public structs and API shape.
Summary
Functions
Return an antenna by its TYPE / SERIAL key.
Load and parse an ANTEX file from path.
Like load/1 but raises on failure.
Parse ANTEX text already in memory.
Frequency-dependent PCO (north/east/up in meters).
Like pco/2 but raises on unknown frequency.
Frequency-dependent phase-center variation in meters.
Like pcv/4 but raises on unknown frequency.
Return the satellite antenna block for PRN prn (e.g. "G05") valid at the
given epoch, or nil if none.
Types
Functions

@spec load(String.t()) :: {:ok, t()} | parse_error()
Load and parse an ANTEX file from path.
Like load/1 but raises on failure.
@spec parse(binary()) :: {:ok, t()} | parse_error()
Parse ANTEX text already in memory.
@spec pco(Sidereon.GNSS.Antex.Antenna.t(), String.t()) :: {:ok, {float(), float(), float()}} | {:error, :unknown_frequency}
Frequency-dependent PCO (north/east/up in meters).
Like pco/2 but raises on unknown frequency.
@spec pcv(Sidereon.GNSS.Antex.Antenna.t(), String.t(), float(), float() | nil) :: {:ok, float()} | {:error, :unknown_frequency}
Frequency-dependent phase-center variation in meters.
Interpolation is linear in zenith and azimuth. Azimuth is optional: when not given (or when the antenna has no azimuth-dependent rows), the NOAZI row is used.
Like pcv/4 but raises on unknown frequency.
@spec satellite_antenna(t(), String.t(), NaiveDateTime.t()) :: Sidereon.GNSS.Antex.Antenna.t() | nil
Return the satellite antenna block for PRN prn (e.g. "G05") valid at the
given epoch, or nil if none.
