Трансивер

DRU17F16XSE (SKYWARE DR7)

  • RX 10.7-12.75 / 950-2150
    • Low Band 1 : 10.7 – 11.7GHz, Local Oscillator = 9.75 GHz
    • High Band 1: 11.7 – 12.6 GHz, Local Oscillator = 10.6 GHz
    • High Band 2: 12.6 – 12.75GHz, Local Oscillator = 13.8 GHz (Inverted Spectrum)
  • TX 13.75-14.50/950-1450/1700 TX LO 12.800 GHz

Подключение

  • IP: 192.168.0.2

Калибровка

test 3 (Калибровка горизонтального уровня блока сенсоров)

1. Enter the radome
2. Connect to wireless Zone in radome.
3. Enter Menu “System -> calibration”
4. Press button “Invalidate”. This will delete all previous calibration data for Tilt and rate sensors all graphs and table values will be deleted.
5. Start a Telnet session to 192.168.0.2
6. Login with user: *** Password: ***
7. Type: weep 2 1 (this is to disable Eeprom write protection)
8. Type: test 3
The antenna will enter test mode and all brushless DC motors will be powered off and stabilization will be turned off.
9. By hand move the antenna in XEL and EL until the Level on top of the sensor unit is in level
Again type test 3 – tilt sensor is calibrated – rate sensors will continue to calibrate.
Wait until brushless DC motors re-powers
Press Button “Download” under calibration menu in web interface. New calibration data for tilt and rate sensor will be downloaded from ASU to SQL database in BDE.
10. Power cycle antenna by switching off and on circuit breaker
11. Observe that the antenna initialize correctly.
(Note that the antenna will probably enter alarm mode after detecting hall sensor due to polarization not correctly calibrated)

test 5 (калибровка привода поляризации)

При неоткалиброванном приводе антенна не наводится на спутник, останавливается после прохождения стартового теста.

1. Enter the radome
2. Connect to wireless Zone in radome.
3. Start a telnet session to BDE, 192.168.0.2
4. Login with user: ***, password: ***
5. Type: weep 2 1 (this is to disable Eeprom write protection)
6. Type in: “test 5”
The transceiver:
a. Turns CCW to mechanical end stop
b. Turns CW until mechanical end stop,
c. 2-3 degrees out of CW Mechanical end stop
d. Moving CW stopping every 20 degree inserting potentiometer references into Eeprom.
7. Progress and results can be viewed in JRAS “Uc Monitor” where reading 1 and 2 should be
approximately the same. Reading 1 is potentiometer reading when transceiver is rotating CCW and
Reading 2 is when transceiver is rotating CW
8. When sensor unit starts to move, power cycle antenna by switching off and on circuit breaker
9. Observe that the antenna initialize correctly and points towards the satellite.
8. AZ and Elevation offsets for new ASU is not optimized and the antenna may not be able to
perform a direct point and track satellite. If Antenna is not able to track satellite try initiating a
search.
9. When antenna is tracking and signal is optimized, set new AZ and EL offset values by:
a. Enter menu “Configuration ->Pointing”
b. Press button “RefSat”
10. Power cycle BDE and ADE
11. Observe ADE initialisation and that it points to satellite
12. Verify that it tracks the satellite at same AZ and EL angle as theoretical calculated direction, if not
repeat from step 8.

Проблемы с VSAT антенной Jotron Saturn 120

Проблема: Антенна неожиданно теряет спутник и переходит в "непонятный" режим работы. Координаты в веб-интерфейсе (JRAS) не отображаются, сменить спутник невозможно.

При этом адреса

  • 192.168.0.5 (below deck unit cable modem)
  • 192.168.0.14 (Above Deck Modem)
  • 192.168.0.15 (ASU - control unit in antenna) (192.168.0.17 в новых антеннах)

пингуются, то есть связь антенна-контроллер есть.
