The latest episode of the Space Minds podcast features host Mike Gruss interviewing Tim Last, Vice President of Global Business Development at Iridium.
Competition in the Direct-to-Device and IoT Sector
The interviewees outline how the market for direct device connectivity and the Internet of Things is becoming increasingly competitive. They stress that companies must devise innovative business models to stay ahead of new entrants while maintaining a strong focus on network reliability and security.
Approaches to Counter GPS Jamming and Spoofing
A major topic is the vulnerability of GPS signals to deliberate interference and deceptive spoofing. Tim Last explains that Iridium is developing robust receivers capable of filtering out jamming signals and is exploring multi‑frequency techniques to improve resilience.
- Design of receivers with adaptive filtering algorithms to suppress interference
- Use of L1/L2/L5 frequency combinations to enhance positioning accuracy under adverse conditions
- Close coordination with national and international regulators to monitor and sanction sources of jamming
In closing, both experts emphasize that cooperation among satellite operators, device manufacturers, and regulatory bodies is essential to support the growing IoT market and to safeguard the integrity of navigation systems over the long term.
