This general component provides all the necessary functions for a satellite to transmit and receive communication to/from a ground station. This component is an extension of DataTransmitter and adds receiver functionality.
The additional functionality entail: A receiving Antenna component that needs to be linked to this component. Additionally a list of type Ground Station creates the communication links which will be calculated. At each time step it is determined whether the satellite is in site of a ground station. If the satellite is within the elevation limit of the ground station a reception link calculation is done to determine the effective power received by the satellite. The power received and ground station ID is reported. If more than one ground station is in the vacinity of the satellite the link that has the largest received power is reported.

We may also share it with our current and future affiliated companies and business partners, and if we are involved in a merger, asset sale or other business reorganization, we may also share or transfer your personal and non-personal information to our successors-in-interest.
We may engage trusted third party service providers to perform functions and provide services to us, such as hosting and maintaining our servers and our service, database storage and management, e-mail management, storage marketing, credit card processing, customer service and fulfilling orders for products and services you may purchase through our service. We will likely share your personal information, and possibly some non-personal information, with these third parties to enable them to perform these services for us and for you.
We may share portions of our log file data, including IP addresses, for analytics purposes with third parties such as web analytics partners, application developers, and ad networks. If your IP address is shared, it may be used to estimate general location and other technographics such as connection speed, whether you have visited the service in a shared location, and type of device used to visit the service. They may aggregate information about our advertising and what you see on the service and then provide auditing, research and reporting for us and our advertisers.

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.

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.
