Small satellites have a communication problem. Not a metaphorical one. A literal one. The antennas that fit inside nanosatellite form factors are limited in gain, bandwidth, and directional control. They work, but they work like a phone from 2015 works. Functional, frustrating, and clearly not where the technology needs to be.

Aalborg-based GomSpace just joined LUNA, a Danish flagship research project aimed at solving exactly this. The project's full name, Low-loss Multiband Nanosatellite Antennas with High Gain and Mechanical Beam Steering, is a mouthful. The ambition behind it is simpler: build antennas that make small satellites communicate like big ones.

The total LUNA budget is DKK 21.1 million, with DKK 14.9 million coming from Innovation Fund Denmark. GomSpace's share is DKK 8 million (approximately SEK 11.4 million). Partners include Aalborg University and Pri-Dana Elektronik A/S.

The satellite industry loves to talk about launch costs, constellation size, and ground segment innovation. Antenna technology rarely gets the same attention, but it's arguably the limiting factor for what small satellites can actually do.

Current nanosatellite antennas are typically omnidirectional or have fixed beam patterns. That means they broadcast in all directions or in one fixed direction, wasting energy and limiting data throughput. For earth observation, IoT connectivity, and secure communications, you need antennas that can steer their beams, operate across multiple frequency bands, and do it all within a package that weighs a few hundred grams.

LUNA's approach combines low signal loss, superior gain, and mechanical beam steering in a form factor designed for nanosatellites. If it works, it means more data, faster downlinks, and the ability to support multiple mission types with a single antenna system.

GomSpace was founded in 2007 in Aalborg, and it's become one of the few European companies that can claim genuine leadership in nanosatellites. The company serves customers in more than 60 countries and has built a reputation for reliable, cost-effective small satellite platforms.

Denmark's space ecosystem punches above its weight. Aalborg University's satellite program has trained generations of engineers. Copenhagen hosts DTU Space. The Innovation Fund Denmark has consistently backed space technology projects that sit at the intersection of academic research and commercial application. LUNA is the latest example.

GomSpace isn't doing this just for the research papers. Better antennas mean better products for their customers. The company's press release noted that LUNA will deliver more integrated, ready-to-use communication solutions with less integration complexity and better performance. That's product-speak for: we'll be able to sell more capable satellites.

The global small satellite market is projected to exceed $13 billion by 2030. As constellations grow and missions become more demanding, the companies that can offer superior communication capabilities in small form factors will capture disproportionate market share. Antenna technology is a key differentiator, and LUNA positions GomSpace to lead rather than follow.

Three years is a reasonable timeline for antenna development, but space hardware has a way of taking longer than planned. The transition from lab prototype to flight-qualified hardware involves radiation testing, thermal cycling, vibration qualification, and integration testing that can each introduce delays.

The partnership structure helps mitigate that risk. Aalborg University brings fundamental antenna research capabilities. Pri-Dana Elektronik brings manufacturing expertise. GomSpace brings the satellite integration knowledge to ensure whatever comes out of the lab actually works in orbit. That combination of academic, industrial, and end-user expertise is what makes Danish space projects effective when they work, and LUNA has the right ingredients.
