印度空间研究组织（ISRO）定于2026年10月30日星期五当地时间晚上11:51（即格林尼治标准时间18:21），在斯里哈里科塔的萨迪什·达万航天中心执行发射任务 1。此次发射将使用GSLV-F18火箭搭载NVS-03导航卫星，旨在扩充并增强印度自主开发的NavIC星座能力，从而减少该国对外国全球定位系统的依赖 1。
NVS-03作为新一代导航系列的第三颗卫星，在技术配置上进行了多项升级 1。该卫星同时配备国产原子钟和进口原子钟，并在原有L5和S波段信号的基础上增加了L1信号频段 1。其设计覆盖范围不仅包括印度境内，还延伸至边境外1500公里区域，为周边地区提供导航服务 1。尽管NavIC项目此前曾因原子钟故障等问题遭遇挫折，但此次发射被视为推进这一本土GPS替代方案的重要步骤 1。
The Indian Space Research Organisation (ISRO) is scheduled to launch the NVS-03 navigation satellite on Friday, October 30, 2026, at 11:51 p.m. local time (18:21 GMT), aiming to enhance its indigenous Regional Navigation Satellite System known as NavIC 1. The mission will utilize the GSLV-F18 rocket for liftoff from the Satish Dhawan Space Centre in Sriharikota, deploying the third satellite of the next-generation navigation series 1. This deployment represents a significant step toward reducing India's reliance on foreign global positioning systems by bolstering its autonomous alternative 1.
The NVS-03 spacecraft is equipped with both domestically produced and imported atomic clocks, addressing previous challenges within the NavIC program where atomic clock failures had caused setbacks 1. In addition to maintaining existing L5 and S-band signals, the new satellite introduces L1 signal capability to improve service quality 1. Designed to provide navigation coverage across India and up to 1,500 kilometers beyond its borders, this launch underscores ISRO's commitment to advancing homegrown space technology despite past technical hurdles 1.
