Commands Chapter 2 2.5.69 WAASECUTOFF Set SBAS satellite elevation cut-off SBAS This command sets the elevation cut-off angle for SBAS satellites. The receiver does not start automatically searching for an SBAS satellite until it rises above the cut-off angle. Tracked SBAS satellites that fall below the WAASECUTOFF angle are no longer tracked unless they are manually assigned (see the ASSIGN command). This command does not affect the tracking of GPS satellites. Similarly, the ECUTOFF command does not affect SBAS satellites. Abbreviated ASCII Syntax: Message ID: 505 WAASECUTOFF angle Factory Default: waasecutoff -5.000000000 ASCII Example: waasecutoff 10.0 This command permits a negative cut-off angle. It could be used in these situations: • The antenna is at a high altitude, and thus can look below the local horizon • Satellites are visible below the horizon due to atmospheric refraction Field Type Field ASCII Value Binary Value - 1 WAASECUTOFF header - 2 angle ±90.0 degrees Description Binary Format Binary Bytes Binary Offset This field contains the command name or the message header depending on whether the command is abbreviated ASCII, ASCII or binary, respectively. - H 0 Elevation cut-off angle relative to horizon (default = -5.0) Float 4 H OEMStar Firmware Version 1.101 Reference Manual Rev 5 173
