Teletactica has been awarded an Estonian contract to develop EW-resilient comms for drones. The company has built products for Ukraine, received funding, and has now set its sights on Europe.

Ukrainian-Estonian startup Teletactica has been awarded a contract by Estonia’s MoD to develop EW-resistance comms for drones. The R&D funding will cover “command and data links for drones and other robotic systems in contested electromagnetic environments,” a Teletactica representative told Calibre Defence on March 11.
The contract builds on the company’s existing work in Ukraine. There, it has developed an ecosystem of communication products for drone control and video streams. They are designed to be used by most drones and have been used during the war.
The company is “turning this foundation into a new solution that provides tactical, EW-resilient communications and C2 capabilities for unmanned platforms,” the representative said. Russian electronic warfare (EW) has proven very capable of disrupting drones and other comms in Ukraine.
At present, there are reports of Russian systems jamming Ukrainian FPVs by beaming videos to the user’s goggles. Other cases of large area jamming of satellite navigation are also well-documented.
This is a strong driver for the development of EW resistant drone communications systems. Without some element of forward thinking, a force may find that its systems simply don’t work during a war.
“Over the course of the 18-month programme, we will develop prototypes and conduct laboratory and field testing,” the representative said. Adding that testing will include partners in Estonia and the Baltics to demonstrate the system in operationally relevant conditions.
Tech profile: Teletactica and its EW resistant comms
The solution will incorporate three core forms of radio frequency technology to build resilience:
Frequency-Hopping: This technique rapidly switches signal carriers across a broad spectrum. The idea is to prevent an adversary from successfully “locking on” to a single frequency for interception or narrow-band jamming.
Resilient Synchronisation: Provides the precise timing necessary for encrypted radios to stay in sync even when GPS is denied. This ensures that electronic countermeasures do not cause the network to drift and disconnect.
MANET Networking: This creates a self-healing mesh where data automatically reroutes through any available node. A MANET allows the communication link to survive even if specific frequencies or individual units are being targeted by EW.
The synchronisation is an aspect worth mentioning again. This is because radio networks rely on frequent check-ins to make sure they are synchronised. And timing – often provided by satellite – is a key element of getting those check-ins right. If timing is lost, a radio network can begin to break down after around 15 minutes. So, building resilience in that regard is a key component of modern comms.
Calibre comment: Ukrainian defence companies come to Europe
Many of Ukraine’s defence companies were established in 2022, responding to Russia’s invasion. They have rapidly adapted to meeting the country’s demands for the war. However, there is often something of a gap between their current structures and EU regulations. Investment from funds like Green Flag and MITS Capital helps them build the structures and governance needed to enter Europe’s defence markets. Now many of them are making their way into Europe with their war-proven capabilities.
