Short Name: Receiver Velocity Format

Property of niGPS

Specifies the format for specifying the receiver velocity.

Note  If this property is set to LTP(SpeedHeading) when the Trajectory Mode property is set to Script and Trajectory Script Climb Enabled property is set to FALSE, the toolkit automatically sets the Current Vd and Current Ad properties to 0. If the Trajectory Script Climb Enabled property is set to TRUE, you can set the Initial Vd property.

The default value is ECEF.

ECEF (0)

Specifies the Earth-centered Earth-fixed (ECEF) format. Select ECEF when you want to set the receiver velocity in terms of the Initial Vx, Initial Vy, and Initial Vz properties. If you do not specify values for the Initial Vx, Initial Vy, and Initial Vz properties after selecting ECEF, the toolkit uses the default values for these properties. The toolkit does not support ECEF if the Trajectory Mode property is set to Script and Trajectory Script Climb Enabled property is set to FALSE. If you select ECEF, the toolkit ignores the Initial Vn, Initial Ve, Initial Vd, Initial Speed, and Initial Heading properties.

LTP(VnVeVd) (1)

Specifies the local tangent plane (LTP) velocity format. Select LTP(VnVeVd) when you want to set the receiver velocity in terms of the Initial Vn, Initial Ve, and Initial Vd properties. If you do not specify values for the Initial Vn, Initial Ve, and Initial Vd properties after selecting LTP(VnVeVd), the toolkit uses default values for these properties. The toolkit does not support LTP(VnVeVd) if the Trajectory Mode property is set to Script and Trajectory Script Climb Enabled property is set to FALSE. If you select LTP(VnVeVd), the toolkit ignores the Initial Vx, Initial Vy, Initial Vz, Initial Speed, and Initial Heading properties.

LTP(SpeedHeading) (2)

Specifies the LTP speed and heading format. Select LTP(SpeedHeading) when you want to set the Initial Speed and Initial Heading properties. Select LTP(SpeedHeading) when the Trajectory Mode property is set to Script and Trajectory Script Climb Enabled property is set to FALSE. If you do not specify the Initial Speed and Initial Heading properties after specifying LTP(SpeedHeading), the toolkit uses the default values for these properties. If you select LTP(SpeedHeading), the toolkit ignores the Initial Vx, Initial Vy, Initial Vz, Initial Vn, Initial Ve, and Initial Vd properties.
