Follow Grantham Road straight ahead to the stop sign at the main entrance to the University. Northbound on U.S. Route 15 Travel approximately 4 miles beyond the PA 74 North intersection near Dillsburg to the Lisburn Road exit. At the bottom of the ramp, turn right onto Lisburn Road. Follow Lisburn Road to the stop sign at the top of the hill. Continue straight on Lisburn Road and take the first exit of the roundabout onto Grantham Road at the bottom of the hill. Follow Grantham Road straight ahead to the stop sign at the main entrance to the University. Presentations Optical Wireless Communication Abstract Our project investigates a mobile optical wireless networking system enabling reliable transfer of data among multiple nodes with no prior knowledge of node locations. Each node is equipped with a multi-transceiver optical wireless communication (OWC) module with electronic beam steering capability. The multi-transceiver design facilitates in establishing multiple simultaneous OWC links with different neighbor nodes. The proposed system ensures error-free data transfer through fast line-of-sight (LOS) discovery, robust maintenance of OWC links, and utilizing reliable communication protocols. A preliminary prototype of our multi- transceiver multi-node OWC system was implemented by using serial line internet protocol (SLIP), transport control protocol (TCP), and Internet Control Message Protocol (ICMP). SLIP is the basis for all communication in the system, and it allows for the other protocols to be used. For the discovery process, the system makes use of the TCP handshake to establish connections between the nodes. To maintain the connections, a customized application of ICMP was used. The effectiveness of this system was analyzed with results obtained from testbed experiments using the developed prototype. The results from these experiments showed that the proposed system can effectively enable reliable communication among multiple nodes. Radio Telescope Control System Abstract: Many people are familiar with the experience of looking up during a clear night and gazing at the stars. Whether through a telescope, binoculars, or with the naked eye, the night skies provide a provoking image of beauty and wonder as we observe the heavens. The night sky has long fascinated humankind, and observing celestial patterns has brought a wealth of information to mathematicians, physicists, and travelers. A low-cost, small-scale radio telescope can provide university undergraduate students with the ability to learn the basics of radio astronomy, the universe, electromagnetic waves, and electronics by plotting measurements at a common radiative frequency of 1.42 GHz referred to as the “hydrogen line”. This paper presents the design, test, and creation of a control system that contributes to the Penn State Harrisburg IEEE branch’s small-scale radio telescope project. This system employs an embedded subsystem that uses DC motor drivers in a closed-loop feedback configuration to control accurate pointing of a 3-meter dish antenna and communicate with a main system computer over a wired link. The primary objective of the subsystem design is to create a layer of abstraction for the main computer through a set of commands—an application programming interface (API)—that direct the dish antenna in an azimuth-elevation coordinate system. The subsystem integrates several functions onto one custom printed circuit board. For motor control, H-Bridge motor drive and rotary encoder feedback are available. Power is supplied through a low-cost commercial off the shelf (COTS) module. A simple LCD display interface is employed to monitor and control the unit without the intervention of the main computer. A custom command API is deployed over a USB-UART bridge to the main computer, which enables flexible and universal control.
