NorthStar Earth & Space has signed agreements with Kepler Communications to place its space domain awareness sensors aboard Kepler satellites, giving the Canadian company a new path to expand its orbital tracking network without waiting for dedicated spacecraft of its own.
The agreement, announced August 27, will see NorthStar optical sensors hosted on Kepler’s satellite infrastructure. Kepler will also provide the communications layer needed to move collected data from orbit to customers with low latency.
For NorthStar, the arrangement addresses one of the biggest challenges facing its space surveillance business: getting enough sensors into orbit quickly and reliably. Rather than tying each new sensor deployment to the development, launch and operation of a dedicated satellite, NorthStar can use Kepler’s existing and expanding spacecraft platform.
Financial terms and a launch date for the first NorthStar payload were not disclosed.
NorthStar Sensors on Kepler Satellites
NorthStar specializes in tracking satellites, debris and other resident space objects across low Earth orbit, medium Earth orbit and geostationary orbit.
Its Space Information & Intelligence platform combines optical observations with third-party data, analytics, inter-satellite connectivity and increasingly onboard artificial intelligence to maintain what the company describes as continuous custody of objects and potentially threatening activity in orbit.
Under the new architecture, the sensing hardware and spacecraft no longer have to come from the same company.
NorthStar will supply the optical SDA payload, while Kepler provides the satellite platform and communications infrastructure. That separation could make it much easier to add sensors incrementally as Kepler expands its constellation.
It also fits a broader industry shift toward hosted payloads, where sensor operators purchase access to spacecraft capacity instead of financing an entire satellite mission.
Kepler Optical Relay Network
The timing is particularly relevant because Kepler has just moved its next-generation optical relay network into commercial service.
Kepler launched the first 10 satellites in the network aboard a SpaceX Falcon 9 on January 11, 2026. Each spacecraft is approximately 300 kilograms and carries multiple optical terminals along with multi-GPU computing hardware and terabytes of onboard storage.
On August 24, Kepler said the first tranche had reached commercial operations, providing customers with optical inter-satellite communications, onboard processing and hosted-payload capabilities.
The architecture effectively gives NorthStar two things from the same partner: somewhere to place its sensors and a high-speed path for moving the resulting observations.
That combination matters for space domain awareness because the value of detecting an object or maneuver decreases rapidly if observations have to wait for a conventional ground-station pass before they can be processed or delivered.
Kepler’s network is designed specifically to reduce that delay by routing information through optical links and distributed computing infrastructure in orbit.
NorthStar Moves Beyond Spire
The Kepler agreement also marks an important change in NorthStar’s spacecraft strategy following its troubled relationship with Spire Global.
NorthStar originally placed four dedicated space surveillance payloads aboard satellites built and operated by Spire beginning in 2024.
That deployment ultimately became the subject of a major contractual dispute.
NorthStar alleged that one spacecraft was lost and that the remaining satellites failed to perform according to contractual requirements. The company subsequently pursued arbitration against Spire and sought $45.9 million in damages.
On July 31, 2026, an International Chamber of Commerce tribunal dismissed NorthStar’s claims and awarded Spire approximately $12.4 million on its counterclaims. Spire’s SEC filing states that the award is final and binding and that the amount is due from NorthStar.
NorthStar has maintained that its original framework agreement with Spire was never terminated and that it remains entitled to four replacement satellites under that contract.
Whatever ultimately happens between the two companies, the Kepler agreement gives NorthStar an independent route for rebuilding its orbital sensing capacity.
That may be strategically more important than the legal outcome itself.
Faster SDA Deployment
Hosted payloads could significantly change the economics of NorthStar’s expansion.
Building an SDA constellation around dedicated spacecraft means every additional sensor can require a spacecraft bus, power system, communications package, launch slot, licensing process and operations infrastructure.
Using Kepler satellites removes several of those requirements from NorthStar’s side of the equation.
The approach should also make it possible to deploy sensors in smaller increments. Instead of committing capital to another four-satellite block, for example, NorthStar could potentially expand its sensor population as suitable Kepler spacecraft become available.
The companies have not disclosed how many NorthStar payloads are covered by the initial agreement, making it too early to determine how quickly this strategy can restore dedicated NorthStar observations in orbit.
Kepler, however, has considerable flight experience. The company says it has launched 33 satellites to date, while the new optical relay architecture currently begins with the 10-spacecraft tranche launched in January.
NorthStar Public Listing Plans
The change in deployment strategy comes while NorthStar is also preparing for a planned public listing.
In April, NorthStar agreed to merge with special purpose acquisition company Viking Acquisition Corp. I.
The transaction values NorthStar at a $300 million pre-money valuation and includes a fully committed $30 million PIPE financing. The combined company is expected to trade on the New York Stock Exchange under the ticker NSTR if the transaction closes.
NorthStar said proceeds from the deal would help fund sensor payloads, spacecraft integration, deployment and other engineering expenses associated with expanding its network.
The company has also been building its government business. In June, NorthStar announced services valued at more than CAD$40 million over 12 months for the Royal Canadian Air Force’s 3 Canadian Space Division.
That creates additional pressure to turn NorthStar’s sensor architecture into a repeatable operational network rather than a small number of experimental spacecraft.
Why the Kepler Deal Matters
The most interesting part of this agreement is not simply that NorthStar found another satellite provider.
It is that NorthStar may be moving toward a fundamentally less capital-intensive model.
NorthStar’s core intellectual property is in the sensor, object-detection architecture, data fusion and analysis. There is no strong strategic reason it must also own the entire spacecraft supporting each sensor if another operator can provide reliable power, pointing, computing and connectivity.
Kepler is particularly well suited to that role because communications are already central to its business. A surveillance sensor hosted on a conventional satellite can still suffer from data-delivery bottlenecks. A sensor sitting directly inside an optical relay network has the potential to shorten the path between observation and operational intelligence considerably.
That could eventually matter more than raw sensor count.
Space domain awareness is moving toward identifying maneuvers and unusual behavior quickly enough for operators to react, rather than simply building increasingly accurate historical catalogs of where objects have been.
Combining persistent sensing, onboard processing and near-real-time optical transport is therefore a logical architecture.
There is still considerable execution risk. NorthStar has not announced how many sensors will fly, when they will launch or what performance targets the new system must meet. Its previous deployment illustrates how quickly a constellation plan can be disrupted by spacecraft-level problems.
But structurally, the Kepler model looks stronger. NorthStar can concentrate investment on the sensing and intelligence layer while using an established satellite network for infrastructure.
If that architecture performs as intended, the Kepler partnership could become more consequential for NorthStar than simply replacing the satellites it lost from its original deployment plan.
