Alicat Mass Flow Meter Used in R&D

Alicat Mass Flow Meter Used in R&D

  The CNSP team has been working on research and development projects the past few months. One of our requirements with these projects is to accurately measure gas volume and gas molecules.   The Alicat Scientific Mass Flow Meter with totalization allows the CNSP team to fill with a precise number of gas molecules on the ground, so the lift and volume of the gas at altitude is just right. The accuracy in measuring the lift gas is...

Little Python Saves Big on Iridium SBD

Little Python Saves Big on Iridium SBD

Iridium Integration Challenges As mentioned in our previous posts, we are beginning to develop more sophisticated payloads. One of the features that we are adding is two-way global communications with Iridium. As payloads become more complex a number of issues pop up. First, the total labor required to design, program, and test the payloads. But the increase in effort is non-linear. Every interface, every additional programmer, and every...

Our Introduction to Iridium

Our Introduction to Iridium

Mission: Global, Two-Way Comms While APRS has served as the primary tracking system on our previous missions, the idea of having two-way communications capability in all geographic areas is appealing. We have investigated satellite communications for our future missions. Starting out, we considered several services, including: OrbComm Globalstar Iridium After talking with fellow balloonists and evaluating the options, we decided Iridium...
