The company NanoRacks has a system installed in the Japanese Kibo module on the Int. Space Station that ejects small CubeSat satellites into orbit. Over 100 satellites have now been deployed by NanoRacks. This video shows the deployment of satellites in 2014:

One of the CubeSats deployed in the past week includes STMSat-1, which was assembled and tested by elementary students at St. Thomas More Cathedral School in Arlington, Virginia: Elementary School Students Make History with Help from Orbital ATK.
St. Thomas More Cathedral School is now the first elementary school in the world to launch a CubeSat into orbit thanks to financial and volunteer support from Orbital ATK’s Space Systems Group. Over the last three years, 400 pre-kindergarten through eighth grade students have participated in all aspects of the project, from design, to construction, to testing.
The CubeSat, officially known as St. Thomas More (STM) Sat-1, will photograph the Earth and transmit images to remote ground stations throughout the country, engaging more than 10,000 grade school students who will participate via Remote Mission Operations Centers.
Joe Pellegrino, Orbital ATK engineer, NASA deputy project manager and a parent at the school, served as the team’s mission manager and led the students through all aspects of getting a mission off the ground.
“Usually these are built by universities or even grad students, so it’s quite remarkable that we’ve been able to do this with grade students,” said Pellegrino. “We taught the students about design philosophy how to do computerized design. The students also helped us with a vibration test. We even did a high altitude test in the parking lot of the school.”
The CubeSat is four inches long and weighs close to three pounds. It was carried to space on Orbital ATK’s Cygnus cargo resupply spacecraft as part of NASA’s Education Launch of Nanosatellites IX mission in December of 2015. Along with CubeSats from the University of Colorado Boulder and the University of Michigan, STMSat-1 deployed from the NanoRacks CubeSat Deployer on May 16. The students expect to start receiving their first images this week.
