APIStrat 2016 | Flying Dreams: Real-Time Communication from the Edge of Space (Jonathan Barton, Neha Abrol)

Creating flexible, resilient access to real-time sensor data can be challenging – especially when your device targets can literally disappear off the face of the Earth! See how groups of students and instructors are using the goMake API to talk with high-altitude balloon telemetry as it skirts the edge of the stratosphere, and the design considerations involved in making this a scalable platform for project-based STEM learning that aims to instill a sense of wonder.

18. Overview The goMake API provides flight related information and real time telemetry for a goMake high altitude balloon and other project launches.

20. Infrastructure - Overview - Circle Ci- Continuous integration - Microservices Architecture with Kubernetes on Google Cloud Node Deployment Service Load Balancer ClusterIP Persistent Volume Service Web Server Container Deployment Mongo Container
21. Infrastructure - Choice Considerations 1. Flexibility - Very fine control of compute usage over time. - Scale up and down based on requirements. 2. Cost: Competitive rates for compute and storage. 3. Availability: Relatively easy to deploy highly-available services. 4. Simplicity: Straight-forward API with command line in- terface and Web UI.
22. Testing Strategies and Data Setup Unit Tests - mongoose-mock - mocking mongoose connection. - sinon-mongoose – chained mongoose model methods. - sinon-stub-promise –promises. Integration Tests - http-status - http responses from endpoints. - supertest-as-promise - mocking requests. Data setup-Mock Data - gomake-mock-data – repository published as an npm package to provide mock data. Data setup-Seeders - gulp populate - “populate” task to copy data from json files to mongoDb collection. npm pack- age gulp-mongo populator used.
23. Challenges - Challenge : No information from satellite during course of the flight. - Solution: To give some kind of predictive navigation information based on previous flights‘ data. (Future implementation). - Challenge : Relationship between flight and telemetry, if same satellite modem is used. - Solution : Have flight launch date with IMEI number as a unique identifier. - Challenge : Working with predefined message formats from on- board devices. - Solution : Still trying to figure out the best yet consistent solu- tion for different consumers like using geoJson
24. Data Security - JWT token– transferring claims. - Auth0 API – authentication and authorization. All user related info is going to be stored in Auth0 database. - SendBird Chat – Each user will get their own chat key.
