ORIENTIRLASH BURCHAKLARIGA OID MASALALAR YECHISH

Ishdan maqsad: Oriyentirlash burchaklari va ular orasidagi munosabatlarni o‘rganish.

Nazariy materiallar.

Oriyentirlash burchaklari. Oriyentirlash burchaklari orasidagi munosabatlar. Haqiqiy va magnit azimutlar.

5-variant

Topshiriq. 1. To‘g‘ri azimut (A) va meridianlar yaqinlashish burchagi () yordamida teskari azimut (A) ni hisoblash.

A' = A + 180° +  A = 51°25′  = 1°15′

A' = 51°25′+180°+1°15′ = 232°40′

Topshiriq. 2. Magnit azimut (A_M) va magnit strelkaning og‘ishi () bo‘yicha haqiqiy (geografik) azimut (A_H) ni hisoblash.

A_H = A_M+ A_M = 125°30′  = +0°52′

A_H = 125°30′ + 0°52′ = 126°22′

Topshiriq. 3. Azimut (A) va meridianlar yaqinlashishi () bo‘yicha deriktsion burchak () ni hisoblash.

 = A -  A = 7230  = +105

 = 7230 - (+105) = 41°56′

Topshiriq. 4. Direktsion burchak () bo‘yicha rumbni (r) hisoblash.

 = 13528 II - 90<₂<180 - JSH_Q – r = 180-

r = 180-13528 = 45°32′

Topshiriq. 5 To‘g‘ri direktsion burchak () bo‘yicha teskari derektsion burchak () ni hisoblash.

 =  + 180  = 7352

 = 7352 + 180 = 253°52′

TO‘G‘RI VA TESKARI GEODEZIK MASALALAR

Ishdan maqsad: To‘g‘ri va teskari geodezik masalalarni yechishni o‘rganish.

Nazariy mateliallar.

To‘g‘ri va teskari geodezik masalalar.

5-variant

Topshiriq. 1. To‘g‘ri geodezik masala.

X₁ = 191389,84; Y₁ = 12495751,42; d_1-2 = 182,85930; _1-2 = 181249; X₂ =?, Y₂ =?

R = 181249

x_1-2 = d*cos*r = 182.85930* cos*181249 = 173.697

y_1-2 = d*sin*r = 182.85930*sin*181249 = 57.154

X₂ = 182.85930+173.697 = 356.5563

Y₂ = 182.85930+57.154 = 240.0133

Topshiriq. 2. Teskari geodezik masala.

X₁ = 191389.84; X₂=191301.33; Y₁=12495751.42; Y₂=12495832.52

=180°- = 137°30′06″
