TimeAzEl

Time-tagged azimuth elevation pointing data.

Specifies the antenna pointing direction at a specific time offset from the segment's reference epoch.

Contents

az

Azimuth angle at the specified time.

Valid ranges by unit:

  • DEGREE_ANGLE: -180 to 360 degrees, measured clockwise from true north

  • RADIAN: -π to 2π radians, measured clockwise from true north

Type: Double

Required: Yes

dt

Time offset in atomic seconds from the segment's reference epoch.

All dt values within a segment must be in ascending order with no duplicates.

dt values may be:

  • negative

  • expressed as fractions of a second

  • expressed in scientific notation

Type: Double

Required: Yes

el

Elevation angle at the specified time.

Valid ranges by unit:

  • DEGREE_ANGLE: -90 to 90 degrees, where 0 is the horizon, 90 is zenith, and negative values are below the horizon

  • RADIAN: -π/2 to π/2 radians, where 0 is the horizon, π/2 is zenith, and negative values are below the horizon

Type: Double

Required: Yes
