Pakistan’s increasing capability in satellite surveillance is prompting concern in New Delhi, particularly following the launch of six Earth-observation satellites over the past 16 months. This development significantly boosts Pakistan’s ability to monitor activities in the region. Most of these missions have reportedly received considerable backing from China, marking a pivotal advancement in Islamabad’s space programme.

The new satellites are expected to provide Pakistan with improved imagery and reconnaissance capabilities, thus enhancing its strategic awareness along its borders. This growing satellite constellation has triggered discussions among India’s strategic and security communities, especially considering that despite India’s existing advantages in launch capacities and deep-space exploration, Pakistan’s advancements in surveillance technology have narrowed the crucial gap in space-based intelligence.

These developments have heightened the urgency for India to address its own navigation capabilities, particularly as rival nations progress in satellite technology.

India’s NavIC System Challenges and Recovery Plans

India is contending with several challenges related to its indigenous navigation satellite system, known as NavIC (Navigation with Indian Constellation). Designed to function as India’s answer to GPS, NavIC aims to provide precise positioning, navigation, and timing services across India and its surrounding areas. However, the performance of the constellation has been impacted by technical issues, particularly concerning the atomic clocks used in the satellites and the ageing spacecraft currently in operation.

The Indian Space Research Organisation (Isro) has established a comprehensive recovery strategy aimed at restoring the full operational capability of NavIC. A significant aspect of this plan is the development and deployment of the second-generation NVS satellite series. The upcoming satellites, NVS-03, NVS-04, and NVS-05, are intended to replace older satellites and bolster the overall efficacy of the constellation.

These new satellites will also support the L1 frequency band, facilitating better compatibility with a broader array of commercial devices and global navigation systems. A critical advancement in this initiative is the adoption of indigenous atomic clocks. Previous NavIC missions relied on imported clock systems, which posed long-term reliability concerns.

Launch Challenges for Isro

As Isro works to implement its recovery strategy, it faces significant challenges due to a recent launch bottleneck. The agency is addressing the issues stemming from consecutive failures in two PSLV missions, with investigations ongoing into the specific causes of these anomalies. Currently, Isro has not publicly shared detailed information regarding the corrective actions being taken to remedy the situation and return the PSLV rocket to operational status.

Until the PSLV is cleared for future launches, Isro must prioritise its missions within a progressively congested launch schedule. High-profile projects, including essential NavIC replacement satellites, await approval to move forward. This predicament intensifies as the competition for space capabilities in South Asia evolves into a strategic imperative.

Space analysts suggest that these developments indicate diverging trajectories in the regional space race. While Pakistan rapidly expands its surveillance reach with Chinese collaboration, India is concentrating on reinforcing vital infrastructure that supports navigation, defence, transportation, and national security. As the competition in space assumes greater strategic importance, Isro’s efforts to enhance the NavIC system may become critical for India’s future capabilities.
