About Lynk Lynk is the inventor of satellite direct to standard phone technology aka sat2phone, and has the world's only commercial license from the FCC to operate a commercial sat2phone system. Today, Lynk allows mobile network operators' subscribers to send and receive text messages to and from space via standard unmodified, mobile devices. Lynk's service has been tested and proven on all seven continents, has regulatory approvals in more than 30 countries and is currently being deployed commercially based on more than 40 MNO commercial service contracts covering approximately 50 countries. Our technology will enable all 8 billion people on the planet to stay connected with the existing standard phone in their pocket. Everywhere. No matter what. By joining Lynk, you will have the opportunity to directly touch the lives of billions. Your mission will be to bring mobile broadband to billions, pull hundreds of millions out of poverty, and save countless lives. Job Summary As a GNC Engineer at Lynk, you will be responsible for the analysis, design, implementation, optimization and enhancement of satellite attitude determination and control systems (ADCS) for the satellites in our constellation. Some of your work products will include satellite ADCS system level design; flight code and algorithm design; ADCS component evaluations of sensors, effectors, etc.; ADCS component design; full hardware in the loop simulation of satellite dynamics in the lab; and design of lab test environments and setups to support ADCS development and testing. Core Responsibilities A GNC Engineer at Lynk will straddle engineering work in the domains of electrical, mechanical, and software engineering. Continue to evolve Lynk's satellite ADCS architecture including components and systems that provide both relative and absolute attitude measurements. Refine the Concept of Operations for the satellite attitude determination and control system and related ground systems. Interface with Systems Engineering team to inform constellation and network architecture and design based on satellite attitude determination and control system performance. Support development of the 6 DOF simulation used to support attitude determination and control system evaluation. Perform analyses to determine satellite ADCS component performance requirements including performance characteristics, such as sizing, accuracy, sensor noise, reliability, redundancy, and fault management options. Specify, evaluate, and select satellite attitude determination sensors which may include rate sensors, magnetometers, sun sensors, horizon sensors, thermal sensors, and star trackers. Specify, evaluate, and select satellite attitude determination effectors which may include magnetorquers, reaction wheels, gravity gradient booms, and even propulsive components. Determine attitude determination sensor and effector types, number, and placement required on spacecraft. Design and implement algorithms and software to support various pointing modes and attitude control scenarios. Evolve Concept of Operations for both ground and space system operations needed to support satellite attitude determination and control. Perform integration and test of satellite ADCS components and software on the satellites and in the lab. Design and plan payload testing configurations on the ground when testing satellite attitude determination and control system performance both in-lab and on-orbit. Support satellite integration, testing, and delivery to launch providers. Develop and maintain technical documentation for satellite ADCS architecture definition, design, and development.
