“…Los satélites Sentinel-1 tienen órbitas casi polares con un desfase de 180º en el mismo plano, de tal forma que cada satélite visita una zona determinada de la superficie terrestre al menos una vez cada 12 días, y cada zona de la superficie terrestre es visitada por alguno de los dos satélites al menos una vez cada 6 días [1]. [2].…”

“…Si bien la técnica de interferometría diferencial a partir de imágenes de radar de apertura sintética no es algo nuevo (las misiones ERS de la Agencia Espacial Europea se remontan a 1991), sí que lo es la resolución, frecuencia de revisitación, cobertura y disponibilidad de imágenes que ofrece la misión Sentinel-1 del Proyecto Copernicus [1] (iniciativa conjunta de la Agencia Espacial Europea y la Comisión Europea), lo que posibilita nuevos usos y aplicaciones.…”

“…Accurate modeling of these forces is required for precise orbit determination of GNSS satellites (Fliegel et al 1992;Rodríguez-Solano et al 2012;Arnold et al 2015;Steigenberger et al 2015;Darugna et al 2018;Bury et al 2019 (Sośnica et al 2014;Panzetta et al 2018), and several Earth observation satellites such as Swarm ), radar altimeter and radar imaging satellites Peter et al 2017;Hackel et al 2017). LEO gravity field recovery missions, e.g., Gravity Recovery and Climate Experiment (GRACE; Tapley et al 2004), CHAllenging Minisatellite Payload (CHAMP; Reigber et al 2002) or ESA's Gravity field and steady-state Ocean Circulation Explorer (GOCE; Floberghagen et al 2011), carry space-borne accelerometers to remove non-gravitational forces from measured orbit perturbations.…”
