  • Page 16: System Theory & Algorithm

    4.1 Searching Method The KNS satellite antenna system uses a step tracking algorithm as a tuning method for searching the satellite. This algorithm works with the moving stabilized antenna and measuring the signal variation that whether the signal level decreases or increases. The antenna is continually moved by fractions of a degree in 3 axis, monitoring for the strongest signal level.

  • Page 17: Tracking Method

    The KNS’s tracking system is the best choice due to the simplicity to implement without loss of performance. KNS signal analysis technology allows to calculate the target satellite position relate to the antenna beam.

  • Page 18: Rssd Threshold

    When the DVB AGC level is above the preset threshold level, the antenna recognize itself that it points toward the target satellite. Thus the threshold level value should be carefully selected to complete the searching process. 4.3.3 RSSD Threshold In this method, the RSSD measures about 250 KHz of the power spectrum at its tuned center frequency and represents its signal strength as an RSSD level (higher is stronger).

  • Page 19: External Agc Threshold

    Also the lock bit delay time can be set to zero when user selects “External RHGER Lock Delay: NO” on the “Auto Beam Switching Protocol” menu (the antenna immediately requires the lock bits from modem). The searching process is made in 7 stages of searching range. The antenna changes the searching range from 1 to 7 as shown below in numerical order.

  • Page 20: External Lock Bit & C/N Threshold

    searches the satellite by measuring the signal according to the AGC threshold level provided by external device which has same function as a built-in DVB tuner. This information can be used for searching in the same manner as the RSSD or DVB AGC threshold.

    which has a stronger carrier level than desired carrier. 4.4.3 DVB C/N Ratio By using the dish scan, the system measures the C/N ratio change of the desired DVB carrier on the target satellite. The DVB tuner C/N ratio is very useful when there is adjacent satellite interference (ASI).

Reference Searching If the target carrier of the desired satellite and the carrier of the adjacent satellite have the same parameters (frequency, symbol rate, FEC, etc.), the antenna may look for the carrier of the adjacent satellite.

  • Page 23: Searching Standard

    4.6 Searching Standard MK3 Z7 DVB-S2 has four searching standard methods: manual pointing, auto, DVB S1, DVB S2, DSS. The user can select the proper method according to desired carrier. 4.6.1 Auto In this searching method, PCU analyze the signal from the desired carrier by using DVB tuner to track the carrier and it takes certain time to search the carrier.

    The ACU can change the target satellite upon receiving the modem protocol (iDirect, iDrtABS, ComROAM, HNS, STM VACP) or the KNS protocol (GTP) from the external device. This function is the ‘Automatic Beam Switching (ABS)’. The ACU receives the ABS protocol via the Ethernet port.

    The installer and operator can access to the ACU from outer devices by using the Ethernet. Configuring the host IP address, gateway, and subnet-mask is required to use the Ethernet. We provide remote access software (SCS & T-Monitor) to the dealer. Under the necessity to obtain this software, contact KNS dealer.

  • Page 102: Appendix C- Acu Compass Connector Pin Layout

    Appendix C- ACU Compass Connector Pin Layout The KA-180 ACU works with Synchro, step by step, and NMEA gyro types and the gyro cable is connected to the ACU with using either a terminal strip connector or a DB-15 connector. Making this connection can be hazardous.
  • Page 103 3. NMEA Type Gyro For the NMEA type gyro, use the 8 (RX+) and 15 (RX-) pin of the DB-15 connector or the RX+ and RX- pins of the NMEA strip connector. Depends on the NMEA type, the cable connection fall into two configuration as shown below.
  • Page 104 5. NMEA Connector The GPS attached on the PCU allows the PCU to know the approximately current location on the surface of the Earth and the PCU sends this data to ACU via DB-9 NMEA (RS232) or RJ-45 console port. However, if GPS is not working for certain reason, the PCU sends default value to ACU which is saved data gathered from GPS antenna.

    Appendix E – Troubleshooting Understanding the symptoms will help the operator to find out what causes the system malfunction and any broken parts. Therefore, the operator may perform the easy repair task. There might be many check point steps in one symptom. If problem is solved on the first step, no longer required to take further steps.
