78910111213141516171819202122Store EEPROM - Used to store in EEPROM the 1030 or 1090 configuration currentlydownloaded in the SQTR-3. Press the Store in EEPROM and a warning button (Figure 4)will pop-up with the stating that storing the information will take approximately 3.5 minutes.Press the “Yes, Continue” or “No, Cancel” button.1090 GPS Coupled - Used to set the time applicability of the 1090 position messages. GPSCoupled On means that the latitude and longitude of the targets are set exactly to the 0.2second UTC epoch to which the position data is extrapolated. GPS Coupled Off means thatthe latitude and longitude are extrapolated to the time of message transmission.1030/1090 Mode - Used to select the SQTR-3 Start-Up Mode for 1030 and 1090. Press theMode button and the SQTR Generator Mode 1030/1090 screen shown in Figure 3 will popup. Mode 0 is the default mode where the user must configure the SQTR-3 1030 and 1090functions. For Mode 1, the SQTR-3 at power-on will load the 1090 configuration stored inEEPROM and wait for the user to press the 1030/1090 Run button (item 11) to begintransmitting 1090 ADS-B (GUI must be re-connected to SQTR-3. For Mode 2, the SQTR-3at power-on will load the 1090 configuration stored in EEPROM and run the scenario untilthe time specified in the Set Scenario Run Time Length (item 16). For Mode 3, the SQTR-3at power-on will load the 1090 configuration stored in EEPROM and run the scenario untilthe time specified in the Set Scenario Run Time Length (item 16) and then keep repeatingthe scenario. For Mode 4, the SQTR-3 at power-on will load the 1030 configuration storedin EEPROM and wait for the user to press the Run button (item 11) to begin transmitting1090 ADS-B (GUI must be re-connected to SQTR-3. For Mode 5, the SQTR-3 at power-onwill load the 1030 configuration stored in EEPROM and continuously run the scenario. If theSQTR-3 has been sent a Mode 1, 2, 3, or 4, a Mode 0 must be sent to the SQTR-3 in orderto return to normal operation where a new scenario can be configured and loaded.RF Level - Used to set the RF level of the 1030 and 1090 transmissions from 13 to -91dBmStandby/Run/Stop - Used to control scenario – Run starts scenario, Standby pausesscenario (hit Run to continue), and Stop (hit Run to re-start scenario)Exit Program – Used to exit and close GUIScenario Status – Indicates if 1030 or 1090 scenario is running (green), in standby (yellow)or stopped (red)Non-Stop – Used to set scenario as configured with Waypoint settings to continuously runversus using Scenario Run Time Length (item 15)Set Scenario Run Time Length and Scenario Elapsed Time – Used to show scenario runand stop times as configured with Waypoint settings and the elapsed time for the 1030 or1090 scenario.UAT Mode – Used to select the SQTR-3 Start-Up Mode for UAT. Press the Mode button andthe SQTR Generator Mode 1030/1090 screen shown in Figure 6 will pop-up. Mode 0 is thedefault mode where the user must configure the SQTR-3 UAT function. For Mode 1, theSQTR-3 at power-on will load the UAT configuration stored in EEPROM and wait for theuser to press the UAT Run button (item 18) to begin transmitting 1090 ADS-B (GUI must bere-connected to SQTR-3. For Mode 2, the SQTR-3 at power-on will load the UATconfiguration stored in EEPROM and run the scenario until the time specified in the SetScenario Run Time Length (item 21). For Mode 3, the SQTR-3 at power-on will load theUAT configuration stored in EEPROM and run the scenario until the time specified in the SetScenario Run Time Length (item 21) and then keep repeating the scenario. If the SQTR-3has been sent a Mode 1, 2, or 3, a Mode 0 command must be sent to the SQTR-3 in orderto return to normal operation where a new scenario can be configured and loaded.Standby/Run/Stop - Used to control scenario – Run starts scenario, Standby pausesscenario (hit Run to continue), and Stop (hit Run to re-start scenario)Scenario Status – Indicates if UAT scenario is running (green), in standby (yellow) orstopped (red)Non-Stop – Used to set scenario as configured with Waypoint settings to continuously runversus using Scenario Run Time Length (item 20)Set Scenario Run Time Length and Scenario Elapsed Time – Used to show set scenario runtime and the elapsed time for the UAT scenario.RF Level - Used to set the RF level of the UAT transmissions from 0 to -101 dBmGPS Simulator – Used to internally generate 1 PPS timing signal if external GPS signal notavailable for SQTR-3SQTR-3 Operators ManualMay 20099

Press the Store in EEPROM and a warning button (Figure 5) will pop-up withthe stating that storing the information will take approximately 3.5 minutes. Press the “Yes,Continue” or “No, Cancel” button.Download UAT - Used to download the configuration or scenario for UAT ADS-B from thecontrol computer to the SQTR-3 (a screen will pop-up indicating that the configuration isbeing downloaded to the SQTR-3).Save to File – Used to store the current configuration currently downloaded into the SQTR-3.UAT/1090 or UAT/1030 is saved in a file on the control computer. Use the Browse button toselect the location for the file. Type a name for the file to be saved and then press the SaveScenario button to store the file. If you are going to replace a file or use the name of anexisting file, use the Browse button to locate the file and press save. A message will pop-upasking if the file is going to be replaced – press Yes, and then press the Save Scenariobutton to store the file.Read from File – Used to load a configuration file that was previously stored on the controlcomputer. Use the Browse button to locate the file. Select the file to be loaded. Press theLoad Scenario button to load the file. The file must then be downloaded into the SQTR-3using the appropriate Download buttons (items 7 and 26) – the control computer must beconnected to the correct Ethernet port for downloading.Figure 1Figure 2Figure 4Figure 3SQTR-3 Operators ManualFigure 5May 200910

1.5.2Manual CommandsA list of manual commands for the SQTR-3 is contained in Appendix A of this manual. Scenarios can be createdfor each of the three functions using MS Notepad. After creating the scenario file, it can be downloaded to theSQTR-3 using Tera Term Pro Web (see Section 1.3). Each time that a scenario is configured and downloadedfrom the GUI to the SQTR-3 (1030 MHz Interrogation, 1090 Squitters, or UAT messages), the SQTR-3 generatesthree files in the directory containing the SQTR-3 program. The three files (1030 commands, 1090 commands orUAT commands) can be used by a new user of the SQTR-3 to view an example of the structure of the commandsused to generate a scenario. This is useful for learning how to manually program the SQTR-3.SQTR-3 Operators ManualMay 200917
