from the sending Earth Station
Satellite
Technologies Satellite
The basic principle of satellite communication is a radio communications system with satellite as repeater stations. Configuring a satellite communication system is divided into two parts: ground segment and space segment. Earth segment consists of several earth station that serves as the sending earth station and earth station receiver, while the space segment of satellite that receives signals transmitted from the sending earth station, and then strengthen it and send signals to a receiving earth station.
In a satellite communication system using geosynchronous orbit, the distance that must be taken very far, which is about 36,000 km. This causes damping trajectories become very large, so that the received power level is very weak. To overcome this problem, a high reliability equipment is necessary, both from the space segment and earth segment.
In accordance with the altitude of its orbit, the satellite mobile communication system consists of three types of orbits:
Feature:
- Low Earth Orbit (500 km to 2,000 km).
- Medium Earth Orbit (5,000 km to 20,000 km)
- Geosynchronous Earth Orbit (35,786 km)
GPRS
Technologies General Packet Radio Services
This a packet-based wireless communication service that promises data rates from 56 up to 114 Kbps and continuous connection to the internet for mobile phone and computer users. The higher data rates allow users to take part in video conferences and interact with multimedia web sites and similar applications using mobile handheld devices as well as notebook computers. GPRS is based on Global System for Mobile (GSM) communication and complements existing services such as circuit-switched cellular phone connections and the Short Message Service (SMS).
Hybrid
Technologies Hybrid
It makes possibly to use the GSM Network or automatically switch to Satellite Network, when the fleet moves toward the blank spot area. The device sent out radio waves to the satellite, and any data or information emitted through this device will be received by the ground station, then, processed by the system or application in order to be read as output. Pointrek Hybrid is very suitable for a short-range transport fleet which is more often operating in areas that have GSM networks.
Multimaps
Technologies Multimaps
Our concept of Geographic Information System (GIS) applies multimaps system to have all users a reference for many subjects. We have developed our software by using the following maps:
Feature:
- Low Earth Orbit (500 km to 2,000 km).
- Medium Earth Orbit (5,000 km to 20,000 km)
- Geosynchronous Earth Orbit (35,786 km)
2Way Communication
Technologies Two-Way Communication
Our technology development pioneers two-way digital communication between the vessel and the command center for sending and receiving text messages. The particular terminals have a variety of capabilities and features to assist the users in accessing necessary information about assignments and instructions for unforeseen problems. It also helpful to emergency services such as to relay information of cases back to the command center.
Provided by some control buttons and keyboards, it is built to withstand the harsh treatment that may occur in a moving vessel. The flexible device is designed to enhance communication and allow vessel to operate more efficiently.
