Eutelsat Beam Calibration – KVHTS @ 2.7 degrees East

NWNS project: 23-06-EUT-01

Introduction

Eutelsat Communications launched (7 September 2022) a new-generation high-throughput Ka-band satellite called Eutelsat Konnect VHTS to serve Europe with Ka-band capacity of 500 Gbps. This 6300 kg satellite has embarked the most powerful on-board digital processor ever put in orbit, offering capacity allocation flexibility, optimal spectrum use, and progressive ground network deployment. Currently the satellite is under test and expected to enter in service in the course of 2023.

After a communications satellite is on its target orbit, several routines need to be performed in order to ensure proper performance from the transponders in the payload

NWNS was given Service Order (under valid MSA between Eutelsat and NWNS) to source, implement, and manage “Over The Air (OTA)” test locations under the coverage of the new satellite.

The purpose of the project is calibrating the signal transmitted to – and received from – the satellite hence beam and footprint measurement. Each forward (from satellite to end user) beam needs to be validated as well as the return signal (from end user to satellite).  

This validation requires two approved terminals fully installed and operative at a location specified by Eutelsat.

About the Eutelsat KVHTS satellite under test:

Orbital location: 2.7 degrees East.

NORAD: 53765 – Callsign: TBD

Frequency spectrum: Ka band.

Beacon(s): 11701.60 RHCP, 11704.00 GHz RHCP, 11698.20 RHCP, 11699.00 RHCP

Our basic requirements:

First we need GEO coordinates of a location which meets the requirements and can host two antennas. The technical requirements are very basic including stable power, security and free view to the satellite for two weeks. Such a test location could be anything…even your backyard or the neighbouring supermarket rooftop.

Summarising our requirements:

  • Facilitating availability of a private site/location with proper 24/7 220V power source for 2 weeks.
  • The facility must have space and authorisations to accommodate two 0.74m antennas for the whole period (2 weeks).
  • The antennas must have unrestricted view to the satellite orbital location (for KVHTS this is 2,7 degrees East).
  • Capability to install 2 identical Hughes system in the same location following the instruction of the Konnect installation guide that will be provided by Eutelsat. Note the KVHTS system is Ka band and has a 70 cm antenna. 
  • Ability to install and commission the station and to interact with the NWNS NOC and Eutelsat teleport operation team (program management).

Important:

  • Technician must install and commission the site together with NWNS and Eutelsat NOC. After commissioning tech must be available within 48h working hours to support the NOC in case of issues that require local support.
  • After two weeks or after “successful completion notification” site must be deinstalled, decently packed and removed from the premises. Equipment either will be reused for a new location, returned to depot, or picked up for return shipment.

Installation:

Regarding the physical installation, everything is easy and straight forward. Expected installation time per antenna is about 60 minutes (probably less). All what’s needed is a wrench key and a screw driver. A spectrum analyser is not needed. A laptop and inclinometer are.

Logistics:

Basically all logistic and shipping services (including equipment supply, importation, delivery and pick-up of the complete kits) are provided by Eutelsat. Occasionally your support and assistance may be required.

A complete kit includes a transceiver, cable, connectors, antenna, and modem. Upon request a non pen mount can be included in the shipment. Eutelsat however prefers to have this item sourced locally. Pole diameter is 60 mm (must double check).

Alternatively, the kit typically contains a tripod mount that can be used for wall mounting or mounting on e.g. a pallet.

One (1) full kit is packed in a single carton with the following dims:
98 cm x 72 cm x 26 cm – 23 kg

Each individual kit includes:

  • 1 modem
  • 1 tria
  • 1 coax cable roll of 30m + f connectors
  • 1 trimast (wall mount / creative mount constructions)
  • 1 antenna (reflector 74cm and az/el top mount)

Eutelsat Beam Calibration – E10B @ 10 degrees East

NWNS project: 23-06-EUT-02

Introduction

The new Eutelsat Communications E10B satellite was launched on 23 November 2022. Scheduled to enter service in Q3/2023. The satellite will be located at 10° East and will carry two new multi-beam HTS Ku-band payloads. E10B will also carry two wide beam C- and Ku-band payloads to ensure service continuity for existing customers on the E10A satellite.

NWNS was given Service Order (under valid MSA between Eutelsat and NWNS) to source, implement, and manage “Over The Air (OTA)” test locations under the coverage of the new satellite.

The purpose of the project is calibrating the signal transmitted to – and received from – the satellite hence beam and footprint measurement. Each forward (from satellite to end user) beam needs to be validated as well as the return signal (from end user to satellite).  

This validation requires two approved terminals fully installed and operative at a location specified by Eutelsat.

 

About the Eutelsat E10B satellite under test:

Orbital location: 10 degrees East.

NORAD: 54259 – Callsign: TBD

Frequency spectrum: Ku band (and C band).

Beacon(s): TBD

Our basic requirements:

First we need GEO coordinates of a location which meets the requirements and can host one antenna. The technical requirements are very basic including stable power, security and free view to the satellite for two weeks. Such a test location could be anything…even your backyard or the neighbouring supermarket rooftop.

Summarising our requirements:

  • Facilitating availability of a private site/location with proper 24/7 220V power source for 2 weeks. Note: estimated power consumption per unit per day is about 2.4 kWh.
  • The facility must have space and authorisations to accommodate one 1.2m antenna for the whole period (2 weeks).
  • The antenna must have unrestricted view to the satellite orbital location (for E10B this is 10 degrees East).
  • Capability to install the VSAT system following the instruction of the installation guide that will be provided by Eutelsat. Note the E10B system is Ku band. 
  • Ability to install and commission the station and to interact with the NWNS NOC and Eutelsat teleport operation team (program management).

Important:

  • Technician must install and commission the site together with NWNS and Eutelsat NOC. After commissioning tech must be available within 48h working hours to support the NOC in case of issues that require local support.
  • After two weeks or after “successful completion notification” site must be deinstalled, decently packed and removed from the premises. Equipment either will be reused for a new location, returned to depot, or picked up for return shipment.

Installation:

Regarding the physical installation, everything is easy and straight forward.

The satellite antenna can be installed on a ground pole, wall/roof mount, or non-penetrating roof mount with a 76mm (3.0-inch) outside diameter mast. The chosen mount type should be assembled and in place before installing the antenna.

Expected physical ODU installation time=is about 60 minutes (probably less). A spectrum analyser is not needed but may be convenient. The elevation scale is somewhat accurate but an inclinometer will safe you lots of time. Note: the modem cannot be used for satellite finding without proper configuration first. It will only show a lock after beam selection and final configuration to be done by Eutelsat. Therefore, Eutelsat will ask you to install “Anydesk” on your laptop or PC and to provide access to your screen. This is the way how they want to do modem configuration.

The installation manual can be downloaded from here. Please note the manual is a bit vague on how to logon to the modem. You receive an email with the exact instructions.

The JSON script file can be downloaded from here (unzip first before uploading to the modem).

Logistics:

Basically all logistic and shipping services (including equipment supply, importation, delivery and pick-up of the complete kits) are provided by Eutelsat. Occasionally your support and assistance may be required.

A complete kit includes a transceiver, cable, connectors, antenna, and modem. Upon request a non pen mount can be included in the shipment. Eutelsat however prefers to have this item sourced locally. Pole outside diameter is 76 mm (or 3″).

One (1) full kit is packed on a single pallet (dimensions 1.50m x 1.50m x 0.40m).
