Radar Vision Boom: Why High‑Res SAR Imaging is Skyrocketing Toward 2030

Radar Vision Boom: Why High‑Res SAR Imaging is Skyrocketing Toward 2030

The global high-resolution SAR imaging market was about $5.4 billion in 2024 and is forecast to reach about $11.6 billion by 2030, a CAGR of roughly 13%. Capella Space had around 10–15 satellites in 2024 delivering 0.5 m and 0.25 m resolution imagery, while ICEYE operates the world’s largest SAR constellation with 20+ satellites. Recent commercial SAR missions have achieved sub-meter resolution, with Umbra reporting ~25 cm imagery and Capella demonstrating ~30 cm and 25 cm-class products. NASA-ISRO’s NISAR mission will carry both an L-band and an S-band radar on the same satellite. North America accounted for about 33.8% of

Oceanography and the Eye in the Sky: How Satellites Are Redefining Our Oceans

Oceanography and the Eye in the Sky: How Satellites Are Redefining Our Oceans

Since 1993, TOPEX/Poseidon and the Jason series have produced a continuous global mean sea level record, showing a rise of about 3.1–3.3 millimeters per year with acceleration to over 4 millimeters per year in the last decade and by 2023 the global mean sea level was over 100 millimeters higher than in 1993. Seasat (1978) carried a radar altimeter and, during its 105-day mission, provided ocean data that followed GEOS-3’s 1975 testing of radar altimetry. TOPEX/Poseidon, launched in 1992, carried two altimeters (NASA Ku/C-band and CNES Poseidon) and achieved sea-surface height accuracy of about 2–3 centimeters on a 10-day repeat

Satellite Imagery: Principles, Applications, and Future Trends

Satellite Imagery: Principles, Applications, and Future Trends

The first space images were captured in 1946 from a sub-orbital U.S. V-2 rocket at about 105 km altitude. The first actual satellite photograph of Earth was taken on August 14, 1959 by the U.S. Explorer 6 satellite. In 1960, TIROS-1 transmitted the first television image of Earth from orbit, a milestone for weather observation. Landsat 1, launched in 1972, began the longest-running civilian Earth-observation program with a 50-year archive, and Landsat 9 was launched in 2021 to continue it. The KH-11 KENNEN program began near-real-time digital imaging in 1977, eliminating the need for film return. IKONOS, launched in 1999,
