GPS 음영 지역 극복을 위한 INS/초음파 속도계 결합 항법 시스템 설계

최근 도심지, 터널, 지하도 등과 같이 위성항법시스템 (GPS; global positioning system) 신호 수신이 어려운 환경에서 안정적으로 정확한 위치 해를 획득하기 위한 다중센서 결합 기법들이 활발하게 연구되고 있다. GPS 음영 지역에서의 위치 정확도를 개선하기 위하여 본 논문에서는 초음파의 전파 특성을 활용하여 동체의 전방 속도를 추정할 수 있는 저가의 초음파 속도계 (ultrasonic-speedometer)를 설계하였고, 이를 활용하여 관성항법시스템 (INS; inertial navigation system)과 효율적으로 결합하는 INS/초음파 속도계 결합 항법 시스템을 제안하였다. 제안된 시스템의 성능을 분석하기 위해 차량 탑재 실험을 수행하였다. 실험결과에 의하면 저가의 MEMS IMU (micro electro mechanical systems inertial measurement unit)를 활용하고 GPS 신호가 10초 이상 가용하지 않는 경우에도 제안된 INS/ 초음파 속도계 결합 항법 시스템은 위치 정보 정확도의 열화를 효과적으로 제한할 수 있음을 확인하였다. Recently, multi-sensor integration techniques have been actively studied to obtain reliable and accurate navigation solution in GPS (Global Positioning System)-denied harsh environments such as urban canyons, tunnels, and underground roads. In this paper, we propose a low-cost ultrasonic-speedometer utilizing the characteristics of the ultrasonic propagation. An efficient integrated INS (inertial navigation system)/ultrasonic-speedometer navigation system is also proposed to improve the accuracy of positioning in GPS-denied environments. To evaluate the proposed system, car experiments with field-collected measurements were performed. By the experiment results, it was confirmed that the proposed INS/ultrasonic-speedometer system bounds the positioning error growth effectively even though GPS signal is blocked more than 10 seconds and a low-cost MEMS IMU (micro electro mechanical systems inertial measurement unit) is utilized.

This study investigates the effect of commercial district ratio on the price of mercantile shops in the case of twenty eight Seoul metropolitan residential land development sites (RLDS). The research method is four types of multiple regression, namely linear, semi-log, inverse semi-log, and log-log model. The dependant variable is the demanding price per square meter of a mercantile shop for sale. The sample analyzed is three thousand and eighty units of shop. Among all models, the log-log one appears to be most persuasive. The facts found through it are summed up as follows; Firstly, the price of a mercantile shop comes 1) under negative influence of its own size (SIZE), the public district ratio (PDR) in the RLDS which it belongs to, the commercial district ratio (CDR), the neighbourhood utility district ratio (NUDR), the time elapsed (TE) since the completion of the RLDS development, and the distance of the RLDS from Kang-Nam Gu, Seoul (DK), 2) under positive influence of the stories number of the building (SNB) which it belongs to and the whole land size (WLS) of the RLDS, and 3) under positive or negative influence of the direction of the RLDS from Seoul City Hall and the floor which it belongs to. Secondly, judging by variable groups, the one most influent to the price of a mercantile shop proves to be the variables concerning to the shop`s own characteristics, and the one secondly influent is confirmed to be the variables related with the RLDS` features, and the variable group concerned with the land use pattern of RLDS turns out to have relatively weak effect on the price. Thirdly, nevertheless, among the variables concerned with the land use pattern, the commercial district ratio (CDR) appears to exercise statistically very significant influence over the price.

1. CONTENTS (1) RESEARCH OBJECTIVES This study investigates the effect of the features of residential land development site (RLDS) on mercantile shop’s rent in the case of Seoul metropolitan area. (2) RESEARCH METHOD The research method is four types of multiple regression, namely linear, semi-log, inverse semi-log, and log-log model. The dependant variable is the demanding rent per square meter of a mercantile shop, The sample analyzed is four thousand two hundred and ninety eight units of shop. (3) RESEARCH FINDINGS Among all models, the log-log one appears to be most persuasive. The facts found through it are summed up as follows: Firstly, the rent per square meter of a mercantile shop comes 1) under negative influence of its own size (SIZE), the commercial district ratio (CDR) in the RLDS which it belongs to, the time elapsed (TE) since the completion of the RLDS development, and the distance of the RLDS from Kang-Nam Gu, Seoul (DK), 2) under positive influence of the stories number of the building (SNB) which it belongs to and the whole land size (WLS) of the RLDS, and 3) under positive or negative influence of the direction of the RLDS from Seoul City Hall (DS) and the building floor which it belongs to. Secondly, judging by variable groups, the one concerning to the shop’s own characteristics proves to be more influent to the rent than the one related with the features of RLDS. Thirdly, judging by individual variables, SIZE, FFD(first floor dummy), and DK reveal more intense effect on the rent in the order. Finally, CDR, TE, DK. WLS, and DS, all of which are connected with the RLDS’ features, appear to exercise statistically very significant and strong influence over the rent. 2. RESULTS The features of RLDS turn out to have statistically very significant and strong effects on mercantile shop’s rent.
