Sequoia Space

Sequoia Space offers consultancy services in the development of satellite missions to government, defence and education institutions. The consulting packages are composed by workshops and permanent accompanying stays during conception, development, launch and operation of the satellite mission.

Sequoia Space offers services of software development and made-to measure applications of both conditions and objectives of earth observation satellite missions, as well as the capture and delivery of telemetry packages.

Sequoia Space represents several companies around the world that provide launch services in different orbital configurations. Sequoia performs the legal management and also makes consultancy about technical procedures and tests related to the demands of companies that perform launches to low orbits.

The Sequoia Space NUKAK-1 (PN: 347010-N1-3U) bus is a platform implemented and set to bear payloads , which are intended to meet the goals in earth observation and remote sensing missions. The NUKAK-1 bus has all systems required for the development of the satellite mission, configurable according to the customer’s specific demands. Sequoia Space Nukak-1 is available for 1U, 2U y 3U dimensions of the Cubesat standard.

The Sequoia Space Getting Started Board (PN: 347001-02) is a hardware development platform to introduce the work teams in the usage of onboard computer resources and the integration with external resources and sensors. The GSB combines the processor’s hardware features and the power of the real time operative system SALVO RTOS or embedded operative systems and could be set as a “Payload” simulator by using the following incorporated components: magnetometers, accelerometers, current and voltage sensors, gyroscopes, temperature systems and GPS module (Optional). PC-104 Form.

The (transmitter UHF/receptor VHF) Sequoia Space transceiver, permits the operation in the radio amateur bands (depending on the assigned ones) with a 1200bps and 9600 transmission speed, modulation FSK, 1200Hz/2200Hz (Bell-202), protocol AX.25 fully compatible with the CSK bus and the ability of being replicated in other formats. The system is designed to accomplish with all minimum necessary requests for 1U and 3U CubeSat missions, allowing the mission to transmit data (telemetry) and at the same time receive data (commands) fulfilling all the features and standards the hardware should comply  during the flight segment in space.

The SEQUOIA earth station offers a communication structure that operates in VHF, UHF bands and S band (only in reception). The proposed solution is designed for the small satellite follow-up, located in low orbit as it is the case of Cubesats or Oscar series satellites.

The design for the SEQUOIA earth station allows its configuration and control by means of the use of Internet and its equipment and configuration which makes it compatible with the GENSO Global Educational Network for Satellite Operations.

The Sequoia Space® sub-orbital probe is directed to the scientific segment, as well as the research of phenomena that occur in the atmosphere. It is composed with a hardware platform that performs monitoring tasks with sensors that capture information during the ascent in a high capacity balloon. The system incorporates an earth station that receives the information that has been captured and transmitted through a communications system in the segment in flight. It is also equipped with a parachute that protects the load when it is extended and an HD camera used to take pictures and video during the flight.

Sequoia Space has the capacity of making specialized montages of clean room components with class 100 HEPA filter. The Clean Room is a room specially designed to obtain low levels of pollution. These rooms have to have particle pollution control, made and used to minimize introduction, generation and retention of particles in the room, where temperature, humidity, air flow patterns, air movement and pressure are controlled. Other relevant parameters such as temperature, humidity and pressure are controlled according to especretentionificaciones and are necessary to make the montage and assembly of solar panels and the final integration of the satellite that would fly to the space.

The source of heat is based on infrared heaters which transfer heat to the sets by means of radiation and use fans to force the hot air to the sets (which are combined with ceramic infrared heaters). That way it can be configured with a temperature profile where the PCB is submitted and then, it is possible to get a uniform welding during the assembly process in the oven.
