CubeSat Launch and Deployment
Getting your CubeSat into orbit is a critical phase. This tutorial explores common launch options for CubeSats, including rideshare missions on larger rockets (e.g., Falcon 9, PSLV), dedicated small satellite launchers, and deployment from the International Space Station (ISS). We'll discuss standard deployers (like P-PODs), the launch environment, and initial post-deployment steps.

Getting a Ride to Space
Because CubeSats are small and standardized, they can often "hitch a ride" on rockets launching much larger primary satellites. This is known as a rideshare or secondary payload launch.
The CubeSat Deployer
CubeSats are not just bolted to the side of a rocket. They are held in a standardized, box-like mechanism called a deployer. The most common is the Poly-Picosatellite Orbital Deployer (P-POD).
- It protects the CubeSat during the intense vibrations and forces of launch.
- It has a door and a spring mechanism to safely eject the CubeSat into orbit once the rocket reaches the correct altitude and velocity.
- It ensures the CubeSat only turns on after it has safely cleared the launch vehicle.
Launch and Early Orbit Phase (LEOP)
This is the critical period immediately after deployment.
Deployment
The deployer door opens and a spring pushes the CubeSat out into space.
Power On
A deployment switch is released, allowing the CubeSat to power on after a safety delay (usually 30-60 minutes).
Detumbling
The satellite stabilizes its initial post-deployment spin.
First Contact
The CubeSat deploys its antennas and begins transmitting a beacon signal. The team on the ground waits to hear this first sign of life.
