[7] The RCM will provide the world's most advanced, comprehensive method of maintaining Arctic sovereignty, conducting coastal surveillance, and ensuring maritime security. [10], Working alongside industry partners, the Canadian Space Agency (CSA) is in charge of mission planning and operations from their headquarters in Saint-Hubert, Quebec. The launch of the second and third RCM spacecraft is planned for late 2017. Learn about NRCan's Role in the RADARSAT Constellation Mission. Figure 19: RCM baseline data reception stations (image credit: CSA, Ref. The SAR antenna is a C-band, active phased array antenna that employs transmit and receive (T/R) modules, distributed across the antenna aperture. Grâce à leur capacité d’intervalle de survol rapide, les satellites pourront capter exactement la même vue du même endroit à la surface de la Terre une fois tous les quatre jours au lieu d’une fois tous les 24 jours, comme c’est actuellement le cas avec RADARSAT-2. A look back at RCM milestones, starting with the planning phase in 2004. • Ice monitoring: The largest operational user of Canadian SAR data is the Canadian Ice Service (CIS). The uplink is a CCSDS-compatible digital bit stream modulating a STDN subcarrier, with a bit rate of 4 kbit/s. Modèles pour impression 3D, jeu numérique, activités amusantes pour les jeunes. For each pulse transmitted, both H and V polarization are received. Who uses RADARSAT data and how, applications and benefits of satellites in our everyday lives. The RCM's goal is to provide data for climate research and commercial applications including oil exploration, fishing, shipping, etc. [2][9] Originally booster B1050 was planned to be used for this mission. La MCR captera des images des eaux, des terres, des glaces et de l'atmosphère de la Terre pendant le jour et la nuit et par tous les types de temps, y compris en présence de nuages épais, de fumée et de brume. [15], This article is about the upcoming satellite mission. The spacecraft is box-shaped with a single fixed deployable solar panel. The current concept involves three satellites with an option of flying up to six spacecraft. • Oil spills: Satellite SAR has proven to be an effective and efficient method of detecting and monitoring oil spills. The received echo or the replica signal at IF goes through a high speed ADC. 11), Figure 3: Constellation timeline (image credit: CSA, Ref. A functional block diagram of the CE receiver DSP module is shown in Figure 14. Overview of the RADARSAT Constellation Mission, its characteristics and its applications. Il utilise des données de RADARSAT pour gérer ses propres cultures et conseiller ses clients.
