Satellite power reference is the absolute power of one satellite signal with 0dB relative power. When real-time application is turned on, the amplitude on the front panel will be set to satellite power reference. When satellite power reference is changed, the amplitude on the front panel will also be updated.

Start Time (GPS Time)

Sets the start date and GPS time for the scenario simulation. Start GPS Time must be later than 1980-01-06 00:00:00. It is automatically updated by Time of Application (TOA) information in the selected almanac file.

For dynamic scenarios, the start time is automatically updated by the first GGA message in the selected NMEA file.

You can ignore the auto-updated date time and manually enter your own value, but it is recommended to use the same date as the almanac date and make the start time on a 6 second boundary.

Using the Start GPS Time dialog or SCPI commands, you can set the Start GPS Time in the following two ways.

Set Date and Time
Set Week and TOW. Here, Week is the week number from 1980-01-06 and TOW is the number of seconds from the start of the current week.

Whichever way you use, the specified set of values result in automatic calculation of the other set of values. For instance, if you set the Date and Time values, then the Week and TOW values are automatically calculated.

Satellite Settings

The Satellite Settings tab displays the satellite information after playing, and is also used to enable/disable and set the power for each played satellite.

When State is set to On:

Settings listed in the table below are visible and their values are refreshed per second.
"Enabled", "Relative Power (dB)", and "Absolute Power (dBm)" settings are editable.

Setting	Name	Description
Ch	Channel	Physical Channel Number
SVID	Space Vehicle ID	G means GPS. E means Galileo. B means BeiDou.
Enabled	Enabled
Freq	Frequency Band	It can be: L1 and L5 for GPS E1 and E5 for Galileo B1I/B1C and B2a for BeiDou
Relative Power (dB)	Relative Power in dB	These two settings are coupled. If one is changed, the other will change to the correct value.
Absolute Power(dBm)	Absolute Power in dBm
Elevation	Elevation	Displays the angle of elevation of the satellite, in degrees. Elevation is the angle of elevation from the horizontal line to the line from receiver to satellite.
Azimuth	Azimuth	Displays the azimuth of the satellite, in degrees. Azimuth is a horizontal angle that starts from the north and goes clockwise.
The following figure illustrates the azimuth and elevation. Elevation ranges from -90 to 90 degrees and the zenith is 90 degrees. Azimuth ranges from 0 to 360 degrees. 90 degrees is the east and 180 degrees is the south.
Pseudorange(m)	Pseudorange in meter	Displays the pseudorange of the satellite with respect to the receiver, in meters. This value is calculated based on GPS L1.
Doppler Shift (Hz)	Doppler Shift effect in Hz	Displays the instant Doppler shift of a satellite towards the receiver. The value, in Hz, is calculated based on GPS L1.

Querying or setting these settings using SCPI commands is not supported.

Antenna Pattern

Antenna Pattern is used to display the antenna pattern of receiver.

All settings and buttons are read-only when State is On.

Setting Name	Min Value	Max Value	Default Value	Step Size	Description
Enable	N/A	N/A	Off (On)	N/A	Antenna Pattern Enable/Disable
Elevation Resolution	1	90	10	0.01	Set the Elevation Resolution

Loss	-60	0	0	0.01	You can single/double-click or tap inside the big circle or double-click/tap outside the circle to select a "grey" region. Then click Apply to apply the Loss (negative dB value).

Save Pattern / Recall Pattern is used to save/recall the settings listed above (except Enable) and the file is csv format.

Sky View

Sky view is used to display the elevation and azimuth of the currently visible satellites, from a receiver’s point of view.

You can move mouse over a particular satellite to display a tooltip, showing detailed real-time information about the satellite, such as SV ID, Power, Pseudorange, and Doppler shift.

For L1+L5 satellite, only pseudorange and doppler shift of L1 are displayed in the tooltip.
For Galileo E1+E5 satellite, only pseudorange and doppler shift of E1 are displayed in the tooltip.
For BeiDou B1i/B1C/B2a satellite, only pseudorange and doppler shift of B1I are displayed in the tooltip.

You can click the legend of each constellations to show/hide all satellites in this constellation. This is for Sky view display only and real-time signal is not affected.

The Sky view is empty or displays the previous status of satellites when State is set to Off.

Power View

Power view is used to display the absolute power of each satellite.

The Power view is empty or displays the previous status of satellites when State is set to Off.

Trajectory View

Real-time Trajectory view is used to display the trajectory of receiver.

For Static scenario type, it will be only one point.

You can set the Reference position (Latitude and Longitude) and Max Deviation in the Map View Configuration, and click “Apply”. Or, you can click “Auto” to set the central position and scaling automatically.

The Trajectory view is empty or displays the previous status of satellites when State is set to Off.

Trajectory Generator

The parameters in the Trajectory Generator tab are further grouped into the following three tabs.

General Settings
Trajectory Settings - Various settings in this tab allow you to define the trajectory. There are three types of trajectory segments.
- Wait
- Straight
- Turn
Each segment supports a variety of configurable parameters, including:
- Duration
- Distance
- Acceleration
- Ending Velocity
- Angle
- Radius
- Climb

These parameters allow precise customization of the trajectory profile based on a specific test or simulation requirements.

Trajectory Preview - This tab provides a visual preview of the trajectory that you defined in the Trajectory Settings. The start and destination points are clearly marked in this view to indicate the beginning and end of the trajectory. The following is a sample trajectory preview when the Shape is set to Rectangle in the Trajectory Settings tab.
