ABS-3

ABS-3, formerly ABS-5, which was named Mabuhay 1 or Agila 2 after the Philippine eagle, before being acquired by Asia Broadcast Satellite is a communications satellite launched in 1997. It originally provides telecommunications services for the Mabuhay Philippines Satellite Corporation before being sold to ABS in 2009. It was the first Filipino owned space satellite not acquired while in orbit. Another satellite named Mabuhay, previously known as Palapa B-2P, was acquired from Indonesian company Pasifik Satelit Nusantara a year earlier becoming the first satellite owned by a Filipino entity. Built by Space Systems/Loral, the satellite provides the most powerful coverage in the Asia-Pacific region. It covers the entire continent of Asia east of Pakistan, as well as the Western Pacific west of Hawaii. Its control station is located at the Subic Space Center in the Subic Bay Freeport Zone. The spacecraft was launched by the Long March 3B in its first successful flight and currently orbits at 146°E longitude.

Banu Abs

The Banu Abs (Arabic: بنو عبس‎, lit. "sons of ʿAbs") are an ancient Bedouin tribe from central Arabia. They form a branch of the Ghatafan tribes. They still inhabit the Arabian Peninsula and North Africa. Of the earliest stories concerning this tribe was the famous classical love and war story of Antar and Abla.

Genealogy

The Banu Abs are of the Northern Arabized Arabs, meaning they descend from Adnan. The Banu Abs descend from Abs ibn Bughaydh ibn Raith ibn Ghatafan ibn Sa'd ibn Qais Ailan ibn Mudar ibn Nizar ibn Ma'ad ibn Adnan. They are related to numerous other Arabian tribes, being distant cousins of the Quraysh, Banu Tamim, and Banu Kinanah. The Banu Thibyaan and Mutayr are also descended from Ghatafan. The large and prestigious Banu Rasheed is descended from the Banu Abs; the great-grandfather of the Banu Rasheed is Rasheed al Zaul of the Banu Abs tribe.

History

Absolute value

In mathematics, the absolute value or modulus |x| of a real number x is the non-negative value of x without regard to its sign. Namely, |x| = x for a positive x, |x| = −x for a negative x (in which case −x is positive), and |0| = 0. For example, the absolute value of 3 is 3, and the absolute value of −3 is also 3. The absolute value of a number may be thought of as its distance from zero.

Generalisations of the absolute value for real numbers occur in a wide variety of mathematical settings. For example, an absolute value is also defined for the complex numbers, the quaternions, ordered rings, fields and vector spaces. The absolute value is closely related to the notions of magnitude, distance, and norm in various mathematical and physical contexts.

Terminology and notation

In 1806, Jean-Robert Argand introduced the term module, meaning unit of measure in French, specifically for the complex absolute value, and it was borrowed into English in 1866 as the Latin equivalent modulus. The term absolute value has been used in this sense from at least 1806 in French and 1857 in English. The notation |x|, with a vertical bar on each side, was introduced by Karl Weierstrass in 1841. Other names for absolute value include numerical value and magnitude.
