The Siemens Communications and Siemens VDO Automotive Groups have jointly developed a pocket-sized navigation solution for Java-based mobile phones: Siemens Mobile Navigation is a cost-effective solution for entry into the world of navigation systems – small, light and extremely portable. State-of-the-art satellite and mobile radio technology provide the latest map material and traffic information to mobile phones via online connection, thus turning them into reliable co-pilots.
The family of permanently installed navigation systems has a new member: The mobile phone. Increasing mobility means more demand for mobile navigation devices. Having been awarded full marks for its Symbian-based navigation solution for mobile phones by the German automobile club, ADAC, Siemens now presents a solution for Java-capable mobile phones. With this latest addition, Siemens complements its product portfolio with a mobile navigation solution that is based on an open standard and can be used across all networks.
A simple, one-off activation is all that’s required and the GPS receiver, which you have in your car together with your mobile phone, automatically creates a Bluetooth connection to the mobile. The receiver determines the exact position of the vehicle within a matter of seconds via satellite signals. Even if you interrupt your journey and park in an underground carpark, the device does not have to go through complex repositioning because the memory effect of the receiver lets it find the position of your vehicle in an instant. When entering their destination, drivers can not only select the places last visited, but simply dial the contacts in the address book of their telephones. Airports, railroad stations or gas stations are preset, similar to conventional navigation systems.

Negros Navigation
Negros Navigation Co., Inc. (Nenaco) is one of the oldest domestic shipping companies in the Philippines. Its main hub is Pier 2 in Manila North Harbor.
It was organized and registered with the Securities and Exchange Commission (SEC) on 26 July 1932 for the purpose of transporting passengers and cargo at various ports of call in the Philippines.
In the 60’s Nenaco was the first among the domestic shipping companies to operate brand new, fast and luxurious air conditioned passenger ships. In 70’s , it was first to construct and operate a modern passenger terminal in Manila’s North Harbor and likewise pioneered in offering special cruises to the Philippine tourist spots using its coastwise vessels. In the 80’s , Nenaco launched its containerization program and ushered a new industry trend on the use of Roll-on Roll-off (“RORO”) vessels.
In the 90’s, it became the first Philippine shipping company to be listed in the stock exchange. Proceeds the amounting to P916.86 million from Initial Public Offering (IPO) were utilized to support the “Globalization Program” of the company that involved fleet expansion and service

Classification of Global Navigation Satellite System
GNSS that provide enhanced accuracy and integrity monitoring usable for civil navigation are classified as followsGNSS-1 is the system and is the combination of existing satellite (GPS and GLONASS), with Satellite Based Augmentation Systems (SBAS) or Ground Based Augmentation Systems (GBAS). In the United States, the satellite based component is the Wide Area Augmentation System (WAAS), in is the Mulfirst generation ti-Functional Satellite Augmentation System (MSAS). Ground based augmentation is provided by systems like the Local Area Augmentation System (LAAS).
GNSS-2 is the second generation of systems that independently provides a full civilian satellite navigation system, exemplified by the European Galileo Europe it is the European Geostationary Navigation Overlay Service (EGNOS), and in Japan it positioning system. Thesnavigation systems e systems will provide the accuracy and integrity monitoring necessary for civil navigation. This system consists of L1 and L2 frequencies for civil use and L5 for system integrity. Development is also in progress to provide GPS with civil use L2 and L5 frequencies, making it a GNSS-2 system.¹

What is Global Navigation Satellite System?
Global Navigation Satellite System (GNSS) is the standard generic term for satellite navigation systems that provide autonomous geo-spatial positioning with global coverage. A GNSS allows small electronic receivers to determine their location (longitude, latitude, and altitude) to within a few metres using time signals transmitted along a line of sight by radio from satellites. Receivers on the ground with a fixed position can also be used to calculate the precise time as a reference for scientific experiments.
As of 2007, the United States NAVSTAR Global Positioning System (GPS) is the only fully operational GNSS. The Russian GLONASS is a GNSS in the process of being restored to full operation. The European Union's Galileo positioning system is a next generation GNSS in the initial deployment phase, scheduled to be operational in 2010. China has indicated it may expand its regional Beidou navigation system into a global system. India's IRNSS, a next generation GNSS is in developmental phase and is scheduled to be operational around 2012

Automotive Navigation system
An automotive navigation system is a satellite navigation system designed for use in automobiles. It typically uses GPS to acquire position data to locate the user on a road in the unit's map database. Using the road database, the unit can give directions to other locations along roads also in its database. Dead reckoning using distance data from sensors attached to the drivetrain, a gyroscope and an accelerometer can be used for greater reliability, as GPS signal loss and/or multipath can occur due to urban canyons or tunnels.
Astrogation
The word astrogation, used by science fiction writers beginning in the first half of the 20th century, denotes navigation of spacecraft, either in interplanetary travel or in interstellar travel. The mathematical principles governing interplanetary astrogation were derived by mathematical physicists in the 19th and 20th centuries.
Two tasks define navigation: determining present location, and planning a safe and reliable means of reaching a destination. An example of an interstellar approach to describing the location of Earth is the plaque carried by the Pioneer 10 and Pioneer 11 spacecraft, where pulsars are used as references.
Route planning is greatly affected by means of propulsion, gravitational potential, obstacles and other hazards (such as radiation), and distance or time. Since no known extrasolar star is closer than four light years away, science fiction writers commonly introduce speculative or fictional work-arounds to the awkward time problem. However, some novels such as Encounter With Tiber, co-authored by astronaut Buzz Aldrin (one of the few people to have set foot on the Moon), treat distance and time more realistically as part of the plot.

Air Navigation
The principles of air navigation are the same for all aircraft, big or small. Air navigation involves successfully piloting an aircraft from place to place without getting lost, breaking the laws applying to aircraft, or endangering the safety of those on board or on the ground.
Air navigation differs from the navigation of surface craft in several ways:
Aircraft travel at relatively high speeds, leaving less time to calculate their position en route. Aircraft normally cannot stop in mid-air to ascertain their position at leisure. Aircraft are safety-limited by the amount of fuel they can carry; a surface vehicle can usually get lost, run out of fuel, then simply await rescue. There is no in-flight rescue for most aircraft. And collisions with obstructions are usually fatal. Therefore, constant awareness of position is critical for aircraft pilots.
The techniques used for navigation in the air will depend on whether the aircraft is flying under the visual flight rules (VFR) or the instrument flight rules (IFR). In the latter case, the pilot will navigate exclusively using instruments and radio navigation aids such as beacons, or as directed under radar control by air traffic control. In the VFR case, a pilot will largely navigate using dead reckoning combined with visual observations (known as pilotage), with reference to appropriate maps. This may be supplemented using radio navigation aids.
