Company business areas– Earth Observation– Ground Station Services


KSAT Earth Observation

Focus on SAR missions – Radarsat-1 (1996), Radarsat-2 (2006)– ERS 1 and 2 (1991), Envisat (1/2003)

Near real-time operations (~minutes)

Round the clock near real-time operations

Provision of information services, e.g. Detection of oil spills, Ship positions

Direct downlink within Tromsø, Svalbard, Grimstad coverage areas

Global data access SvalSat, TrollSat and via ESA ground segment

New missions for service continuity and new products and markets

Introducing optical data and services


KSAT Ground Station Services

Svalbard advantages– 14 orbits per day– Direct downlink, global data access– Fiber cable since January 2004

Round the clock operations/services– TT&C

– LEOP Support

– Data reception (S -X band) and distribution

– Back-up and anomally support

Remote operations from Tromsø Network Control Centre (TNOC)

Customers

NASA: Terra, Aqua, ICESat, Coriolis, …

ESA: Envisat, ERS-2, ADM/Aeolus

KSAT ground segment & services

Svalbard = The polar meteorological satellite facility (IPO, Eumetsat)

Troll, Future meteorological site in Antarctica

SAR based services– Oil Spill detection– Ship detection for maritime security– Ice applications/data and services– Wind (speed, direction) information – Land applications

- Snow & Flood mapping and monitoring

Other relevant/optical data and services– Terra, Aqua MODIS data– Coriolis WINDSAT data– TIROS-N NOAA/AVHRR data

Grimstad

Tromsø

Svalbard


KSAT data and derived services

MODIS data, increasing interest– snow cover mapping for hydropower production planning, – flood monitoring. KSAT provides MODIS data and derived products for snow mapping

during the melting season as part of an EU FRP project Envisnow.

Development and provision of marine earth observation services, new oceanographic information services:

– Oceanographic information, wind and waves, is needed to provide reliable services.

– Growing need for wind and wave information to serve the met. communities in Europe.

Potential new services– ”Global” and fast access to (MODIS) optical data for European and

Global users– MODIS polar winds– Coriolis/WindSat service


Coriolis wind information service

Spaceborne wind measurements– ERS scatterometer data less availability– Japanese Adeos-2 satellite failed– Envisat does not operate a scatterometer.

Operational institutional users in Europe such as met. institutes in a more difficult position with respect to service and information availability.

Emerging opportunity recognition– The KSAT capabilities to provide near real-time services – Coriolis Windsat knowledge and the data access via Svalbard, 1) Mission found an increasing interest among European met. institutes. 2) KSAT evaluated how a WindSat processing chain at Svalbard/Tromsø could

meet European needs for fast access to wind speed and direction information. – A Coriolis wind service can and will complement KSAT Envisat ASAR NRT wind

information service


Proposed Coriolis mission and service scenario

Downlink regional mission data to Svalbard and a second KSAT ground station (Tromsø or Grimstad). 4-6 passes per day.

Downlink on-board recorded global data to Svalbard

Supplementary access based on downlink of data to US facilities

Additional stations further South in Europe if required by the users

Raw data distributed via fibre link to Tromsø.

Near real-time distribution of derived wind information via land lines to institutional European users Black line = raw data

Red line = derived information

Direct read out MODIS data

KSAT operational reception of MODIS data– Direct downlink Tromsø, Svalbard and Grimstad– Global dump Svalbard under NOAA/NASA contract

Future MODIS data type continuity, and KSAT operational ambitions for ”one-stop-shop”

– Expand current capabilities and services (web-based technology)– Delivery of (Level 1B) data to users/VA companies– Utilisation of MODIS (-type) data for operational services.

1. Information reliability improvement optical+SAR data e.g algae vs oil spills2. New services based on MODIS-type (Polar winds, snow cover mapping)

Conclusions – The next step

Coriolis mission and the capability is known

Coriolis wind information will be a supplement to European institutional users/VA

Coriolis wind information may be included in KSAT wind service

Develop services based on the use of Svalbard and Troll and ESTABLISH A POLAR WORKING GROUP FOR DB APPLICATIONS
