Simulation model for the Gen2 CubeComputer, running its control program. The ADCS of satellite is a sophisticated and self-contained system. It demands precise timing and synchronisation, robust fault detection, isolation, and recovery (FDIR) mechanisms, comprehensive power monitoring and switching, meticulous logging and telemetry handling, as well as accurate configuration and calibration of sensors. Additionally, it relies on complex mathematical models and algorithms. Over the past decade, our team has meticulously refined our CubeADCS to execute these tasks flawlessly; simplifying a complex subsystem into a customisable and scalable plug-and-play solution. The result is a user-friendly, flexible, and modular ADCS solution, that comes with a comprehensive manual and includes both integration and commissioning support.

We take precautions to protect the security of your information. We have physical, electronic, and managerial procedures to help safeguard, prevent unauthorized access, maintain data security, and correctly use your information. However, neither people nor security systems are foolproof, including encryption systems. In addition, people can commit intentional crimes, make mistakes or fail to follow policies. Therefore, while we use reasonable efforts to protect your personal information, we cannot guarantee its absolute security. If applicable law imposes any non-disclaimable duty to protect your personal information, you agree that intentional misconduct will be the standards used to measure our compliance with that duty.
The rights you have to request updates or corrections to the information we collect depend on your relationship with us. Personnel may update or correct their information as detailed in our internal company employment policies. Customers have the right to request the restriction of certain uses and disclosures of personally identifiable information as follows. You can contact us in order to (1) update or correct your personally identifiable information, (2) change your preferences with respect to communications and other information you receive from us, or (3) delete the personally identifiable information maintained about you on our systems (subject to the following paragraph), by cancelling your account. Such updates, corrections, changes and deletions will have no effect on other information that we maintain, or information that we have provided to third parties in accordance with this Privacy Policy prior to such update, correction, change or deletion. To protect your privacy and security, we may take reasonable steps (such as requesting a unique password) to verify your identity before granting you profile access or making corrections. You are responsible for maintaining the secrecy of your unique password and account information at all times. You should be aware that it is not technologically possible to remove each and every record of the information you have provided to us from our system. The need to back up our systems to protect information from inadvertent loss means that a copy of your information may exist in a non-erasable form that will be difficult or impossible for us to locate. Promptly after receiving your request, all personal information stored in databases we actively use, and other readily searchable media will be updated, corrected, changed or deleted, as appropriate, as soon as and to the extent reasonably and technically practicable.

Such updates, corrections, changes and deletions will have no effect on other information that we maintain, or information that we have provided to third parties in accordance with this Privacy Policy prior to such update, correction, change or deletion.
We reserve the right to transfer information to a third party in the event of a sale, merger or other transfer of all or substantially all of the assets of us or any of its Corporate Affiliates (as defined herein), or that portion of us or any of its Corporate Affiliates to which the Service relates, or in the event that we discontinue our business or file a petition or have filed against us a petition in bankruptcy, reorganization or similar proceeding, provided that the third party agrees to adhere to the terms of this Privacy Policy.
We may disclose information (including personal information) about you to our Corporate Affiliates.

Any information relating to you that we provide to our Corporate Affiliates will be treated by those Corporate Affiliates in accordance with the terms of this Privacy Policy.
We keep your information only so long as we need it to provide service to you and fulfill the purposes described in this policy. This is also the case for anyone that we share your information with and who carries out services on our behalf. When we no longer need to use your information and there is no need for us to keep it to comply with our legal or regulatory obligations, we'll either remove it from our systems or depersonalize it so that we can't identify you.
We implement a variety of security measures to maintain the safety of your personal information when you place an order or enter, submit, or access your personal information. We offer the use of a secure server. All supplied sensitive/credit information is transmitted via Secure Socket Layer (SSL) technology and then encrypted into our Payment gateway providers database only to be accessible by those authorized with special access rights to such systems, and are required to keep the information confidential. After a transaction, your private information (credit cards, social security numbers, financials, etc.) is never kept on file.
