Summary
NVS-02 (IRNSS-1K) is a navigation satellite launched by the Indian Space Research Organisation (ISRO) on January 29, 2025, from the Satish Dhawan Space Centre using the GSLV-F15 launch vehicle. The spacecraft measures 2.4 meters in length with a diameter of 1.6 meters and a span of 9.5 meters when its solar arrays are deployed. It has a dry mass of 1000 kg and was designed for a mission life exceeding 12 years. Equipped with advanced navigation payloads operating in L1, L5, and S bands; ranging payload in C-band; and a Rubidium Atomic Frequency Standard (RAFS) for precise timekeeping, the satellite is intended to enhance India's regional navigation capabilities through the NavIC system. NVS-02 utilizes two solar arrays generating up to 3 kW of power and employs three-axis stabilization. The satellite structure is composed primarily of aluminum and composite materials, painted in silver with white thermal blankets. Post-launch, a propulsion system anomaly occurred, preventing it from reaching its intended orbital slot; ISRO is now exploring alternative mission strategies.
