Patent number: 11204107Abstract: A valve system having a vacuum valve and a regulating unit is disclosed. The vacuum valve has a valve seat including a valve opening, a first seal surface, and a valve closure for closing the valve opening using a second seal surface. A drive unit coupled to the valve closure is designed to be adjusted to provide respective valve opening states. The regulating unit adjusts the valve opening state by actuating the drive unit based on a currently determined regulating variable and a target variable. The regulating unit has a checking function configured such that a series of states of the valve closure are detected as park of the regulating process, and the states are stored as current regulating data. The current regulating data is compared with specified target regulating data and process information is generated based on the comparison of the current and the target regulating data.Type: GrantFiled: November 2, 2017Date of Patent: December 21, 2021Assignee: VAT HOLDING AGInventors: Christoph Böhm, Daniel Seitz

Patent number: 11142346Abstract: A payload interposer (PIP) board provides an interface for hosting payloads on a space vehicle platform. Payload development may be performed via the PIP board in a manner that “abstracts” the hardware of the space vehicle from the payload developer. The PIP board may include a host side payload interface connector that connects to a space vehicle and a payload side payload interface connector that connects to a payload. Power, CDH, and other space vehicle functionality may thus be provided to the payload from the space vehicle via the PIP board.Type: GrantFiled: March 29, 2018Date of Patent: October 12, 2021Assignee: Triad National Security, LLCInventors: Michael Proicou, Adam Warniment, Paul Stein, Nicholas Dallmann, Daniel Seitz, Logan Ott

Patent number: 11046463Abstract: A compact SFS may can be deployed in small space vehicles. The SFS may have a small size, weight, and low power requirements. The hardware, software, catalogs, and calibration algorithm of the SFS provide highly accurate attitude information that can be used for pointing. For instance, accurate attitude determination may be provided that supports pointing of a deployable high gain helical antenna. A full “lost in space” attitude solution, accurate to about an arcminute, may be accomplished in under a minute. The SFS may be fully reprogrammable on orbit, allowing continued algorithm development and deployment after launch.Type: GrantFiled: July 24, 2018Date of Patent: June 29, 2021Assignee: Triad National Security, LLCInventors: Nicholas Dallmann, James Wren, Michael Proicou, Hannah Mohr, Jerry Delapp, Kimberly Katko, John Martinez, Donathan Ortega, Daniel Seitz, Paul Stein, Justin Tripp, Adam Warniment, Robert Wheat, Jr.

Patent number: 11021274Abstract: Small cubesat systems may be available for a lower cost, have a higher reliability, and be much simpler to use than conventional cubesats. A complete turnkey system solution may be provided, including the ground station and remote field units. The satellite, ground station, and field unit may be provided separately as kits that are ready to go out-of-the-box as soon as they arrive. This enables universities, researchers, and hobbyists to obtain and deploy their own functional satellites. Furthermore, theoretical designs and functionality may be rapidly prototyped and demonstrated, which allows for proof-of-concept without needing to build a larger, more expensive satellite system and hope that the new design or functionality works as intended.Type: GrantFiled: September 8, 2016Date of Patent: June 1, 2021Assignee: Triad National Security, LLCInventors: Stephen Judd, Nicholas Dallmann, Kevin McCabe, Donald Enemark, Michael Proicou, Daniel Seitz

Patent number: 10981677Abstract: A “black box” space vehicle solution may allow a payload developer to define the mission space and provide mission hardware within a predetermined volume and with predetermined connectivity. Components such as the power module, radios and boards, attitude determination and control system (ADCS), command and data handling (C&DH), etc. may all be provided as part of a “stock” (i.e., core) space vehicle. The payload provided by the payload developer may be plugged into the space vehicle payload section, tested, and launched without custom development of core space vehicle components by the payload developer. A docking station may facilitate convenient development and testing of the space vehicle while reducing handling thereof.Type: GrantFiled: January 16, 2018Date of Patent: April 20, 2021Assignee: Triad National Security, LLCInventors: Stephen Judd, Nicholas Dallmann, Kevin McCabe, Daniel Seitz

Patent number: 10766640Abstract: A payload interposer (PIP) system and its control software provide an interface between a space vehicle and a payload. The PIP board facilitates power and communications between a command and data handler (CDH) of the space vehicle and the payload. A microcontroller of the PIP board may control operation of the payload, format messages between the space vehicle and the payload, and extract data from the payload for downlink via the space vehicle.Type: GrantFiled: March 29, 2018Date of Patent: September 8, 2020Assignee: Triad National Security, LLCInventors: Michael Proicou, Adam Warniment, Paul Stein, Nicholas Dallmann, Daniel Seitz, Logan Ott

Patent number: 10445110Abstract: A space vehicle may have a modular board configuration that commonly uses some or all components and a common operating system for at least some of the boards. Each modular board may have its own dedicated processing, and processing loads may be distributed. The space vehicle may be reprogrammable, and may be launched without code that enables all functionality and/or components. Code errors may be detected and the space vehicle may be reset to a working code version to prevent system failure.Type: GrantFiled: February 23, 2017Date of Patent: October 15, 2019Assignee: Triad National Security, LLCInventors: Stephen Judd, Nicholas Dallmann, Kevin McCabe, Jerry Delapp, Dean Prichard, Michael Proicou, Daniel Seitz, Paul Stein, John Michel, Justin Tripp, Joseph Palmer, Steven Storms

Patent number: 10351266Abstract: An ADCS module may be configured to use coordinate data from 2D photodiodes in one or more sun sensors to determine a sun vector. The ADCS module may then use the sun vector in reference to its own body faced (BF) coordinate system to calculate a change in the orientation of the space vehicle. The change in orientation mechanism may be accomplished by reaction wheels, ion thrusters, or other orientation altering mechanisms. A miniature, intelligent star tracker may be included that improves satellite attitude determination and pointing accuracy. An improved reaction wheel assembly may be included that is more robust and suitable for inclusion in small space vehicles.Type: GrantFiled: June 22, 2015Date of Patent: July 16, 2019Assignee: Triad National Security, LLCInventors: Stephen Judd, Nicholas Dallmann, Michael Proicou, Daniel Seitz, Paul Stein, John Martinez, Gayle Kestell, Adam Warniment, Steven Storms
