• The spacecraft operation is being done by the CONAE Control Center at Cordoba, Argentina (also location of the Cordoba ground station). 1 cm) on the image represents a smaller true distance on the ground, this image is at a larger scale. And, according to Peres, the SAOCOM will be capable of capturing 500 images as it orbits 15 times a day. However, fine detail would not really be necessary for monitoring a broad class including all vegetation cover. - 10 m x 3.5 m (35m2) SAR ActivePhase Array antenna. The ground segment, includes all the activities from spacecraft monitoring/control to data product generation and distribution. This would also imply that the spatial resolution of the sensor would be fairly coarse. The frequent coverage would also allow for areas covered by clouds on one date, to be filled in by data collected from another date, reasonably close in time. All data processing, archiving and distribution is being provided by the MOC (Mission Operations Center) facility at Cordoba. Each SAOCOM-1 spacecraft (SAOCOM-1A and SAOCOM-1B) has an estimated wet mass of ~1600 kg. For enquiries, contact us. Flying over a city or town, you would be able to see individual buildings and cars, but you would be viewing a much smaller area than the astronaut. 1:100,000), and those with larger ratios (e.g. - SAOCOM -1A features six computers that work in synchronicity; the spacecraft has a mass of 3,000 kg. • Belgium takes also part in the SAOCOM project of CONAE by the joint development of a processor, a simulator and the necessary tools for processing the data from the polarimetric SAR instrument. The SAOCOM L-band system operates jointly with the Italian COSMO-SkyMed constellation in X-band for better coverage of emergency events. 1 cm) on the image represents a smaller true distance on the ground, this image is at a larger scale. 13). - On October 9, the satellite was maneuvered so that its orientation was fixed as it will remain throughout its useful life and will be maintained by the attitude control system. The effort was spearheaded by Dr. Aly Sadek, chairman of the Egyptian Council for Space Science and Technology Research. 16), Figure 9: Engineers prepare to depart Argentina en route to Florida to resume SAOCOM 1B launch preparations (image credit: CONAE). , A consortium consisted of KB Yuzhnoe design bureau and sub-contractors Ukrainian companies:. c) SGS (Svalbard Ground Station), Norway: X- & S-bands. 11), Figure 6: In the early hours of Monday morning (8 October), as Argentina's CONAE space agency launched the SAOCOM-1A satellite into space, photographer William T. Reid captured this dramatic image of Earth's newest admirer catching a lift on the back of a SpaceX Falcon 9 rocket (image credit: William T. Reid) 12). For a homogeneous feature to be detected, its size generally has to be equal to or larger than the resolution cell. They will be tested for the virus again before they are permitted to enter SpaceX facilities at Cape Canaveral, according to CONAE. Maps or images with small "map-to-ground ratios" are referred to as small scale (e.g. The contrast in reflectance between these two regions assists in identifying vegetation cover.The magnitude of the reflected infrared energy is also an indication of vegetation health. Obviously, the SAOCOM-1A spacecraft is operational and providing imagery. 14), Figure 8: A Falcon 9 rocket climbs away from pad 40 Sunday at Cape Canaveral Air Force Station (image credit: SpaceX). RF communications: S-band for TT&C communications and X-band for SAR payload data download at a rate of 310 Mbit/s. - Once on orbit, the satellite will mark CONAE's fifth space mission as it joins the country's two prior orbiting satellites — Arsat-1 and Arsat-2 — which were built by Argentine satellite maker ArSat and launched in 2014 and 2015, respectively. Image pixels are normally square and represent a certain area on an image. Which of the two images is of a smaller scale? After firing engines to slow down, the booster extended landing legs and returned to Landing Zone 1 on Cape Canaveral Air Force Station about eight minutes into the mission, touching down as a powerful sonic boom rippled through an atmosphere thick with humidity. CL-POL: RH/RV or LH/LV, > 350 km The flight dynamics team will continue calculating the satellite's orbit in the following weeks (Ref. As we mentioned in Chapter 1, most remote sensing images are composed of a matrix of picture elements, or pixels, which are the smallest units of an image. < 50 m, 25º - 45º This area on the ground is called the resolution cell and determines a sensor's maximum spatial resolution. TopSAR narrow swath, Signal reception • March 24, 2020: Concerns about the coronavirus pandemic have prompted officials to postpone the planned March 30 launch of Argentina's SAOCOM 1B radar observation satellite from Cape Canaveral aboard a SpaceX Falcon 9 rocket, officials said Tuesday. - The "body" of the satellite (the service platform) and its "eyes" (the radar antenna), with which it will observe the earth, are in communication. If you had a map with a scale of 1:100,000, an object of 1cm length on the map would actually be an object 100,000cm (1km) long on the ground. An onboard mass memory of 256 Gbit is provided. The IFOV is the angular cone of visibility of the sensor (A) and determines the area on the Earth's surface which is "seen" from a given altitude at one particular moment in time (B). The nine Merlin engines on the Falcon 9's first stage shut down about two-and-a-half minutes after launch, then the booster — reused from three previous missions — separated and flipped around to begin thrusting back toward Cape Canaveral. If the IFOV for all pixels of a scanner stays constant (which is often the case), then the ground area represented by pixels at the nadir will have a larger scale then those pixels which are off-nadir. • January 2, 2018: Professionals from CONAE (National Space Activities Commission), CNEA (National Commission of Atomic Energy), and the companies VENG, INVAP and CEATSA/Arsat concluded in Bariloche (Argentina) the electrical verifications and the mechanical assembly of the SAOCOM-1A, the new Argentine observation satellite developed by the CONAE together with other national organizations and companies. 8). The mission design life is 5 years. - The SAOCOM-1B engineers who traveled to Florida tested negative for the COVID-19 virus before departing Argentina. - An Earth observation satellite, SAOCOM-1A will provide welcome new data on our planet, stimulating projects to monitor the planet's forests, map soil moisture and measure surface deformation and motion from space, in the context of natural and anthropogenic disasters. You will not receive a reply. left or right side of path (left side is default), Stripmap high resolution 20º - 35º The SAOCOM-1B satellite has a mass of 3050 kg and is identical to SAOCOM-1A. QP: HH/HV/VH/VV, 21º - 50º The Argentine-built satellite, equipped with a sophisticated radar imaging instrument, separated from the Falcon 9's upper stage about 14 minutes into the mission. The ratio of distance on an image or map, to actual ground distance is referred to as scale. Emergencies, such as floods, droughts, desertification, landslides, oil slicks in land and ocean, fires, seismology, earthquake activity and volcanism, are mainly considered. > 350 km, < 50 m 6). 9). It was the 18th time SpaceX has landed a Falcon 9 booster at Cape Canaveral since 2015, and the 59th successful recovery of a Falcon 9 first stage overall, including landings on SpaceX's ocean-going drone ships.
