Hybrid navigation is the simultaneous use of more than one navigation system for location data determination, needed for navigation. By using multiple systems at once, the accuracy as a whole is improved. It also allows for a more reliable navigation system, as if one system fails, the other can kick in and provide accurate navigation for the user.
The P-791 was designed as part of the U.S. Army's Long Endurance Multi-intelligence Vehicle (LEMV) program, but lost the program's competition to Northrop Grumman's HAV-3 design. The P-791 was modified to be a civil cargo aircraft under the name SkyTug, with a lift capability of 20 short tons (18,000 kg) and plans to scale larger.
d is the distance between the two points along a great circle of the sphere (see spherical distance), r is the radius of the sphere. The haversine formula allows the haversine of θ to be computed directly from the latitude (represented by φ) and longitude (represented by λ) of the two points:
The Hybrid Wireless Mesh Protocol (HWMP), part of IEEE 802.11s, is a basic routing protocol for a wireless mesh network. It is based on Ad hoc On-Demand Distance Vector (AODV) Routing (RFC 3561) and tree-based routing. [1] It relies on a Peer Link Management protocol by which each Mesh Point discovers and tracks neighboring nodes.
An (orange-epoxy) encapsulated hybrid circuit on a printed circuit board (PCB).. A hybrid integrated circuit (HIC), hybrid microcircuit, hybrid circuit or simply hybrid is a miniaturized electronic circuit constructed of individual devices, such as semiconductor devices (e.g. transistors, diodes or monolithic ICs) and passive components (e.g. resistors, inductors, transformers, and capacitors ...
The first work on hybrid rockets was performed in the early 1930s at the Soviet Group for the Study of Reactive Motion. Mikhail Klavdievich Tikhonravov, who would later supervise the design of Sputnik I and the Luna programme, was responsible for the first hybrid propelled rocket launch, the GIRD-9, on 17 August 1933, which reached an altitude of 400 metres (1,300 ft).
Except for the Prius c, sales of the other models of the Prius family and the Camry Hybrid suffered a decline from 2012, while the Fusion Hybrid experienced a 164.3% increased from 2012, and C-Max Hybrid sales climbed 156.6%. [6] 2014. Hybrid sales totaled 452,152 units, down 8.8% from the previous year.
A hybrid electric bus may have either a parallel powertrain (e.g., Volvo B5LH) [1] [2] or a series powertrain (e.g., some versions of the Alexander Dennis Enviro400 MMC). [3] Since 2003, Allison Transmission has produced dual-mode hybrid drive units which take the place of a conventional transmission, mostly for transit buses in North America ...
