For several decades rockets were built to deliver satellites that weigh several hundred or thousand kilograms. None of the launch providers were really interested in just putting satellites into orbit that were the size of a shoebox or typical refrigerator, because of the insignificantly low returns they would get in accommodating these satellites against larger payloads.
However, over the last decade, the CubeSat and small satellite revolution has created a growing demand for launch services for these satellites.
In this article we provide a gentle primer to the topic of how the demand for CubeSat and small satellites has evolved and give an overview of some of the launch service providers currently available on the global marketplace for space.
In the next few chapters we take a brief look at how launch service provision works and discuss what key performance characteristics need to be taken into account when selecting a product for your operation. If you would instead like to skip down to view the product listings, please click here.

The sudden emergence of an avalanche of CubeSats and small satellites in the space industry over the last decade has created a classic problem of demand and supply for space launches. Essentially, because the big rockets had to find a way to accommodate and adapt to servicing multiple CubeSats and other small satellites on their rockets.
Given that only a handful of launches are available for any satellite to get to orbit every year, multiple satellite manufacturers have been trying to get on board launch manifests as quickly as possible to ensure their satellites can deploy and provide services to their customers. This demand-and-supply problem has created an opportunity for service providers who can streamline the entire process of procuring a launch, and the space industry has seen the emergence of several launch service providers.
In this article we look at some of the factors that should be taken into account while selecting a launch service provider. We also provide an overview of a number of launch service providers on the market, all of which are listed on the satsearch platform to help you select the best option.
The lifecycle of launching a CubeSat or a small satellite
Once a satellite is built there are several aspects that need to be taken care of in the process of launching it into space to ensure safety and success:
- Finding a launch slot: Although there are tens of launch vehicles under development in the industry today, reliable launch options are scarce. There is no use for a satellite sitting in a lab and finding a launch slot that coincides with the final assembly of the satellite can be challenging. There are also barriers to accessing certain launch options such as the fact that US satellites are not allowed to launch out of Chinese rockets.
Launcher requirements and contract management: once a launch option is selected the price, window for launch and other aspects such as compliance to the environmental requirements of the rocket need to be agreed.
Use of launch adapters and deployers: Cubesats cannot be integrated directly into a rocket and need deployers or dispensers to get into orbit. Similarly, small satellites of various volumes or masses may not have specific launch interface adapters available from the launch providers. A decision to use a particular deployer, or work with the launch operator to use their adapter, needs to be made as a part of interfacing with the rocket.
Transport and integration: after the satellite is built, integrated and tested it needs to be transported safely, to remote locations where launches are often conducted to integrate it into the rockets. This involves clearance of the satellite through export control, customs, final environmental tests, integration and checkout tests of the satellite into the rocket.
Types of launch options for CubeSats and small satellites
- Launch service providers: Launch service providers enable teams building CubeSats and small satellites to access a launch seamlessly by solving the major problems that satellite manufacturers and satellite-based service providers face in getting to orbit. As the supply of launches are scarce in the industry, launch service providers help plan and discover the optimum launch options catering to the mission, orbit, timeframe and budget.
Launch service providers make life easy for teams trying to launch their satellites by taking the risk of booking a launch with the rocket (launch provider) and offering slots as individual contracts. Once a potential launch provider is selected, the details of interfacing the satellite into the launch vehicle and complying with the requirements of the launch vehicle are all provided on behalf of the launch operator.
Launch service providers package the provision of launch adapters and Picosatellite Orbital Deployers (PODs) so that both the launch provider and the satellite manufacturers don’t need to bother about having the right mechanical and electrical interfaces with the launch vehicle. Once a decision is made to choose a particular launch option, all the legal and regulatory aspects of launch support, provision of the deployers, the necessary environmental tests, transport of the satellite, clearance of customs, running of final tests and integrating the satellite with the rocket is all taken care of by these launch service providers.
- Launch operators who also do service provision: Traditionally, aggregating demand for CubeSats and small satellites was difficult for launch operators, and this is one of the reasons why they depended on service providers to aggregate this demand. For example, the Polar Satellite Launch Vehicle (PSLV) from India has seen tens of satellites being launched into space on multiple campaigns organised by launch service providers such as Spaceflight Industries, who aggregated the demand.
However, this landscape is now evolving with launch operators such as SpaceX and RocketLab themselves looking to provide services. This phenomenon may become bigger as many other small satellite rocket operators may come online to make the entire process of getting to orbit smoother for CubeSat and small satellite manufacturers.
- International Space Station (ISS) based launch services: The ISS is a free flying asset in Low Earth Orbit (LEO) which has been leveraged over the last few years to deploy CubeSats and small satellites. The low orbit of ISS ensures that these satellites have a short life span in orbit and re-enter the Earth’s atmosphere within a few years.
The Small Satellite Orbital Deployer (SSOD) attached to the Japanese module’s robotic arm is used by astronauts who seal the airlock on the ISS, open the other end up to space, and command the station’s Kibo robotic arm to pick up the deployer to bring it outside for satellite deployment. ISS based launch service providers are specific to US and Japan as they are key stakeholders in using the Kibo robotic arm. The ISS can also be used to perform experiments inside the station.
- Orbit as a service: Launch vehicles often deliver satellites into an orbit with a specific inclination, altitude. However, satellites launched as a part of the constellation often need to go into different inclinations so that they can maximize the service area over the Earth’s surface. This can be solved by adding a propulsion device on the satellites, but that will obviously make the satellites more expensive and also add additional weight.
This problem is creating another opportunity in the launch service provision industry to create a service to deliver satellites launched as a part of a constellation on the same rocket to go into different inclinations. We call this the ‘orbit as a service’ model.
- Marketplaces for launch services: Emerging start-ups are testing the possibility of streamlining the launch industry by creating a marketplace for teams seeking out launch opportunities. They may be more widely used once several launch operators mature and tens of reliable options available in the market to choose from.
Now that you’re armed with the knowledge of what are the important aspects to consider in selecting a launch service provider, you can make an informed decision from the available launch service providers, based on your preferences.
