Top Articles - Navigation Satellites
Navigational satellites were one of the early applications of artificial earth satellites. Very e According to USFDA, a combination product is one composed of any combination of a drug and device; biological product and device; drug and biological product arly in the space age, researchers realized that satellites could be put on orbits to permit ship ; or drug, device, and biological product and fixed dose combination would include two or more combinations of drug. Examples of combination products may in , aircraft, or other vehicles to exactly determine their locations. Global positioning systems (G lude drug-coated devices, drugs packaged with delivery devices in medical kits, and drugs and devices packaged separately but intended to be used together. PS) make of navigation satellites. The GPS constellation system was first established by the US m here is enormous increase in the number of combination products entering the market in the recent years. Combination products have proven advantages but fixe litary to support of their forces. But it is now in widespread in public and commercial applicati d dose combinations are still in the process of convincing regulatory authority on their advantages over the single ingredient formulations. Combination pro ns. The navigation equipment generally consists of a sensitive radio receiver, an accurate frequ ucts have become life saving products for the pharmaceutical companies who doesn’t have many innovative molecules in their product pipeline and have been inc ency reference, and an accurate clock. The idea of using satellites for navigation began with the easingly used in the product life cycle management. Even the companies having product patents are trying to extend their product life cycle through the combi launch of Sputnik 1 on October 4, 1957. Satellite navigation systems allow small electronic devic nation products and maximize the revenues. But the companies involved in this practice are overlooking that they are burdening the patients both economically s to determine their location. Navigation satellites were developed in the late 1950's. They are and physically. They need to rightly judge the benefits of the combination products and they have to even look at the risks involved when combining the produ of great help to transportation companies, especially for transportation over water and through ts. Some of the combination products were well accepted by physicians while others suffered. Companies involved in development of combination products are fi he air. Navigation satellite systems help pilots and ship navigators locate their positions and m ding difficulty in defining their combination products and facing various challenges from selecting a combination to marketing it. Following aspects would a ny related information. Navigation satellite systems have a wide variety of civilian uses also. dd to the challenges in developing combination products: Which markets to tap where the combination products can do fairly well? Which combination prod They are used for to measure distances, for instance, between buildings. They are also used to ma cts are meaningful and rational? Which therapeutic categories to select? Which Combinations can address unmet needs of the patients? Do combin e accurate maps of remote areas of earth. GPS Navstar satellites operate at altitudes of 10,000 tions increase the patient compliance? What would be the developing cost? How to tackle the risks encountered during combination product developmen o 20,000 kilometers. In global positioning satellite system (GPS) 24 Navstar satellites are used t? As combination products don't fit into the traditional categories of drugs, medical devices, or biological products, the USFDA is in the process of devel to determine position. Each satellite broadcasts time and position messages continuously. GPS is ping new procedures for reviewing their safety, efficacy and quality. Professional from academic institutions, pharmaceutical industries, health care indust he only fully functional satellite navigation system. The former Soviet Union established a posit y and representatives from various regulatory agencies are working out to design the regulatory requirements for manufacture and sale of combination products oning system equivalent to the Navstar, called the global orbiting navigation satellite system (G . As there is an increasing trend of the combination products companies manufacturing such products should be able to tackle the problems involved in the de LONASS). GLONASS uses the same number of satellites as in Navstar. They use 24 to 27 satellites t elopment. They need to be wiser in analyzing the market trends and the regulatory requirements. Companies that provide selfless information through particip at orbit in three different planes. The first GLONASS satellites were launched into orbit in 1982 tion in industry events and feedback to regulatory authorities would be able to face the challenges and will be successful in developing combination products
