Ogo may refer to:
Ogo is a handheld electronic device which allows the user to communicate via instant messaging services, email, MMS and SMS text messages. The device works through GSM cellular networks and allows unlimited usage for a flat monthly fee. It supports AOL Instant Messenger, Yahoo! Messenger, and MSN Messenger.
Ogo uses the IXI-Connect OS. It features a clamshell design with a 12-bit depth color screen on the top half and a full QWERTY keyboard on the lower half. Navigation through the menus is accomplished primarily through the use of a directional pad located on the lower right hand of the device and alternately through buttons that directly access each of the devices features.
The Ogo is part of a family of devices produced by its overseas manufacturer, IXI, which showcase the "personal mobile gateway" concept, wherein the Ogo acts as a wireless gateway for other Bluetooth enabled devices to access the Internet. Other devices in the family include pens and cameras.
Orbiting Geophysical Observatory (OGO) refers to the six satellites launched by the United States that were in use from September 1964 to 1972, designed to study the Earth's magnetosphere. The satellites successfully studied the interactions between the Earth and the Sun, despite a number of technical problems. Each satellite had 20 to 25 instruments. OGO 1, OGO 3, and OGO 5 were in equatorial orbits; OGO 2, OGO 4, and OGO 6 were in lower polar orbits.
