MDA to provide RADARSAT-2 information to meet critical and complex challenges for land and maritime monitoring

Richmond, BC- MDA, a Maxar Technologies company (formerly MacDonald, Dettwiler and Associates Ltd.), (NYSE: MAXR; TSX: MAXR), announced today it has recently signed multiple geospatial-related contracts based on RADARSAT-2 satellite information. RADARSAT-2 Synthetic Aperture Radar (SAR) imagery provides users with a unique method of accurately monitoring very large areas to locate, track, measure, and monitor objects. A rich source for analytics, SAR imagery reveals important details about our changing planet and the impact of human activity across the globe. The following contracts have a combined value of approximately CA$16 million, and will:

• Extend the provision of RADARSAT-2 information to EarthSTAR Inc., a subsidiary of EarthView Image Inc., up to December 31, 2024. EarthSTAR uses the information for a variety of applications that includes land monitoring and change detection.
• Continue the provision of RADARSAT-2 information to the European Maritime Safety Agency (EMSA). Under this contract, MDA provides RADARSAT-2 information to support EMSA in the areas of maritime safety, maritime security, law enforcement, fisheries control, and marine pollution monitoring.
• Extend the provision of operational support to Canada's Department of National Defence (DND), which includes the use of the east and west coast RADARSAT-2 ground systems for the DND Polar Epsilon Near Real-Time Ship Detection system. DND has activated one of the four one-year renewals under the contract announced September 2017.
• Provide RADARSAT-2 based information services for onshore and offshore monitoring to multiple oil and gas customers.

RADARSAT-2 information can be used for asset monitoring in mining, energy, and other civil markets. MDA has developed a suite of powerful off-the-shelf solutions that exploit SAR imagery and associated information, to support maritime, forestry, infrastructure development, and surveillance applications with high levels of accuracy, and reliability.

Mike Greenley, group president for MDA said, “MDA is focused on supporting our customer’s needs and as a trusted partner is pleased that our customers return to us repeatedly to provide them with accurate, timely and cost-effective information.”
