Mitsubishi Electric Acquires Infostellar: The Day 'Ground Station Sharing,' an Invention from Japan, Entered the Mainstream
On July 1, 2026, Mitsubishi Electric acquired all shares of the Tokyo-based startup Infostellar, making it a wholly owned subsidiary. The acquisition price has not been disclosed.

Honestly, when I first heard about this combination, I felt it was a bit surprising. Mitsubishi Electric is a company with a strong image of being 'heavy, thick, long, and large,' building satellite bodies and ground control equipment in-house. On the other hand, Infostellar is a venture founded in 2016 with several dozen employees. While they may seem like they are from different fields, the objective is actually very logical.
What is GSaaS—The Concept of 'Not Owning Ground Stations'
Infostellar handles a business called GSaaS (Ground Segment as a Service). Through its self-developed cloud platform, 'StellarStation,' the company provides ground segment services for satellites in orbit.
In the past, it was standard for satellite operators to build and maintain their own ground stations. Building parabolic antennas on their own land, installing dedicated lines, and monitoring 24/7. It is a field burdened by massive initial investments and fixed costs.
Infostellar's idea was the opposite. It is to 'share' the facilities of ground station operators scattered around the world. StellarStation is a flexible and scalable satellite ground station sharing platform; once set up, satellite operators can access any ground station included in the global network. Even without owning their own stations, they can 'rent' them when and as much as they need. It might be easier to imagine if you call it the Airbnb of ground stations.
As I mentioned before, with low-Earth orbit satellites expanding to the scale of thousands, ground station infrastructure is becoming a hidden bottleneck in the new space era.
Why was a company of this size acquired now?
What is symbolic about this acquisition is that Infostellar was by no means a large corporation. GSaaS is a system that provides satellite operators with pay-as-you-go access to reserve time and capacity on shared antennas, where multiple users share facilities instead of owning their own stations. Similar startups include Leaf Space, RBC Signals, and Atlas Space Operations, and major players like KSAT and AWS have also entered the market.
In other words, although Infostellar is a pioneer that opened up this field, there is no shortage of competitors. Even so, the reason Mitsubishi Electric chose them seems to lie in the compatibility of their businesses.
Mitsubishi Electric is drawing up a blueprint to combine its long-cultivated development capabilities in satellite and ground equipment with Infostellar's software development prowess. The company has a track record of handling numerous projects both in Japan and abroad, including those for JAXA, and claims to have extensive expertise regarding satellites and ground equipment. While they are experts in hardware like large antennas and control systems, the software culture of turning that into a service on the cloud and adding features with the speed of a startup is, honestly, not something Mitsubishi Electric can cultivate in-house overnight. That is likely why they reached the decision to 'buy'.
Demand Created by Small Satellite Constellations
Behind this acquisition is the industry-wide trend of a rapid increase in small satellite constellations. Through this integration, Mitsubishi Electric's long-cultivated satellite and ground system business will be linked with Infostellar's cloud-based ground segment service platform, 'StellarStation.' The two companies aim to accelerate the deployment of a globally virtualized ground station network through this combination, reducing the burden of initial investment for constellation operators who require frequent communication with satellites.
For operators managing satellite groups on the scale of hundreds or thousands, it is necessary to communicate with each satellite many times a day. It is unrealistic to build ground stations all over the world on their own, which is why the demand for a 'shared ground station network' is rising rapidly.
One Milestone for GSaaS from Japan
Infostellar has attracted international attention as a GSaaS company from Japan. It has expanded its business in parallel with major overseas cloud providers, such as through its collaboration with AWS Ground Station. The development of it now coming under the umbrella of a Japanese heavy electric manufacturer is likely to continue to attract attention as a practical example of the 'fusion of large corporations and startups' in the Japanese space business.
This sense of achievement is also evident in the comments from Infostellar's CEO. The innovative business model for cloud-based ground station services is said to strengthen the Mitsubishi Electric Group's defense and space systems business. The expectation on Infostellar's side seems to be that by gaining the brand power and capital of a large corporation, they can accelerate the construction of a larger-scale ground station network than ever before.
When it comes to the space business, eyes tend to be drawn to rockets and the launch of the satellites themselves. However, what is actually turning data into business is this 'ground' part. This acquisition can be said to be a signal that the capital of large corporations has begun to flow in earnest into that plain but essential layer.
