Background: Small-sided games are frequently used as a training method in today´s football. The importance of the ability to perform high-intensity running is increasing and small-sided games may not lead to the required improvement of this ability. It might be necessary to add speed-endurance training to obtain the high-intensity running. Objective: The aim of this study was to investigate which of the training methods; small-sided games or speed-endurance training, leads to the highest performance improvements in three football-specific tests. Measures and Methods: The study was an intervention study where 31 male football players participated. They were randomized in to two groups which performed either speed-endurance training (SEP) (n=16) or small-sided games (SSG) 6 vs 6 (n=15). The study lasted four weeks and eleven sessions in total. Baseline tests and posttraining test were conducted in Yo-Yo IR2, Arrowhead agility test and Repeated sprint 30 meters. Result: SEP demonstrated an 17 % higher increase in testresults than SSG in Yo-Yo IR2. No significant difference between the groups were observed in the other tests. Conclusion: Small-sided games is a training method which entails football-specific training load. It might be necessary to add speed-endurance training which can lead to higher performance improvments in Yo-Yo IR2.

International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / The Global Positioning System (GPS) is a very accurate, all-weather, world wide three dimensional navigation system and it has been used in almost every field related to positioning and navigation. This paper presents a new application of GPS technology - personal positioning and navigation system. It combines VP ONCORE receiver OEM (Original Equipment Manufacture) board and an intelligent system controller, with a keyboard and a programmable LCD as its peripherals. This system can realize rich navigation functions and satisfy the need of personal use.

International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / In the last few years there has been a proliferation of GPS receivers and receiver manufacturers. Couple this with a growing number of DoD test programs requiring high accuracy Time-Space-Position-Information (TSPI) with diminishing test support funds and/or needing a wide area, low altitude or surface tracking capability. The Air Force Development Test Center (AFDTC) recognized the growing requirements for using GPS in test programs and the need for a low cost, portable TSPI processing capability which sparked the development of the Desktop GPS Analyst. The Desktop GPS Analyst is a personal computer (PC) based software application for the generation of GPS-based TSPI.

International Telemetering Conference Proceedings / October 23-26, 2000 / Town & Country Hotel and Conference Center, San Diego, California / This paper discusses the successful passage past the Year 2000 (Y2K) Rollover and GPS 1999 (Week Number Roll Over) WNRO. The reasons the glitches seen at those events were relatively minor and the lessons learned to help enter the Third Millennium with careful optimism are reviewed.

International Telemetering Conference Proceedings / October 23-26, 2000 / Town & Country Hotel and Conference Center, San Diego, California / Global Positioning System (GPS) technology is being used as a sensor in telemetry systems to provide time, space and position information (TSPI) as well as end game or vector scoring. The accuracy of these measurements depends on precisely locating the phase center of the GPS antenna. A procedure has not currently been addressed by anyone to measure the phase center of a conformal wrap-around GPS antenna. This paper will discuss some techniques on determining the antenna phase center.

International Telemetering Conference Proceedings / October 23-26, 2000 / Town & Country Hotel and Conference Center, San Diego, California / In the past, airplanes, target drones, pods, and large missiles have been instrumented with telemetry, flight termination and beacon tracking antennas to assess performance. With the emerging use of the Global Positioning System (GPS) for tracking purposes, GPS is also included as part of the instrumentation package. This paper addresses the design of a conformal wraparound antenna system to cover the telemetry and GPS L1 frequencies for a small (2.75 inch) diameter airborne projectile. A filter is also integrated into the antenna system to isolate the transmitted telemetry signal from the received GPS signal. This integration is necessary due to the lack of space in the small diameter projectile. Performance characteristics of the prototype antenna system are also presented.

International Telemetering Conference Proceedings / October 23-26, 2000 / Town & Country Hotel and Conference Center, San Diego, California / In the past few years, GPS has proven itself as an effective source of time space position information (TSPI) data for air vehicles. Currently, GPS truth systems are used to track aircraft ranging from low dynamic vehicles to high dynamic fighters. However, low-cost GPS TSPI instrumentation is not currently available for stores and weapons delivered by air vehicles. To date, data is collected by tracking dropped items using radar or optical means. This process is costly and time consuming. The purpose of this project is to leverage the recent advances in micro-electromechanical systems (MEMS) technology to develop a subminiature, inexpensive, low power, disposable telemetrytransmitting package. The purpose of this transmitting package is to up-link the GPS positional data from the weapon or store to the host aircraft. This data is then retransmitted by the host aircraft to a ground station and/or recorded on board for post processing. The transmission of the data to the host aircraft can provide near real- time position data for the released object. The transmitting package must have a unique identification method for application in tracking multiple objects. Since most of the systems used in weapons testing will be destroyed, it is extremely important to keep the development and maintenance cost low. In addition, the package must be non-intrusive to avoid any significant modification to the weapon and to facilitate quick instrumentation of the weapon for test and evaluation.

International Telemetering Conference Proceedings / October 30-November 02, 1995 / Riviera Hotel, Las Vegas, Nevada / Recent narrow band imagery of the surface of Titan reveals a very non-uniform surface. While there are no global oceans of liquid ethane/methane as once conjectured, the imagery does suggest the possibility of seas or lakes of liquid ethane, methane, and other organic materials. If these exist, Titan could be considered a gigantic analog model of the Earth's climate system complete with land masses, moderately thick atmosphere, and large bodies of liquid. By studying the climate of Titan, we could gain further understanding of the processes and mechanisms that shape the Earth's climate. Reuse of existing technology and methods may be a way to speed development and lower costs for the global study of Titan. Surprisingly, one of the key technologies could be a Transit or Global Positioning System (GPS) descendant for use in tracking probes wandering the surface of Titan.
