In order to explore other applications for the GPS receiver,documentation of the interface characteristics for the NMEA, ARINC 429 and the RTCMinterfaces is required.To understand where these interfaces occur in the larger system context, Figure 1 was generated.The TBXL falls in the category labeled Airborne/Marine GPS Receivers. Using signals from theGPS satellites and error correction signals from an Airborne/Marine DGPS Receiver, the TBXLcan internally correct errors in the measurement of range to the satellites, which the TBXL usesto triangulate its position. The range errors, which can be corrected by the DGPS capability inthe TBXL, are errors

Additionally, the model recognizesthat this progression is unique to each individual and therefore is manifested only through one'sown personal philosophy.Active learning is a central theme to this progression for two reasons: (1) Each student enters theclassroom with his or her own set of desired outcomes for the course. Often these outcomes areinconsistent with, or a subset of, the instructor's goals. Active learning empowers each student tocontrol how learning takes place and, in addition, holds them accountable for success (or failure)in obtaining the end

Many schools have implemented new courses and programs which include theseexperiences. Large state universities, however, have specific characteristics which require specialattention. These include: (1) large numbers of students, (2) students entering with a wide diversityof backgrounds, abilities, ages and learning styles, and (3) large numbers of transfer studentscoming from public two-year community colleges and four-year non-specialty colleges.

The primary purpose of this paper is to report on theeffectiveness of this hands-on content. In addition, we will provide an overview of thedivision of the course into redesign and original design sections. The primaryassessment tool being used is a survey which students fill out after each lecture. Eachstudent survey took approximately a minute to complete and was designed todifferentiate between four things: 1) student’s interest in that lecture’s subject matter, 2)that day’s learning experience, 3) their ability to apply material covered that day and 4)their interest in exploring that lecture’s

During the fall of 1997 a set of experiments weredeveloped to assist in the comprehension of mechanics of statics principles by providingconcrete experiences. Hands-on-exercises were developed to support the concepts of forcecomponents, vectors, free body diagrams, moments, two and multi-force members, plane trusses,frames and machines, and internal forces and moments in beams.Introduction“Engineering is a fundamental human process” 1.
